vm: rework stack as a simple slice Double-linked list is quite expensive to manage especially given that it requires microallocations for each Element. It can be replaced by simple slice which is much more effective for simple push/pop operations that are very typical in a VM. I've worried a little about more complex operations like XDROP/1024 or REVERSEN/1024 because these require copying quite substantial number of elements, but turns out these work fine too. At the moment Element is kept as a convenient wrapper for Bytes/BigInt/Bool/etc methods, but it can be changed in future. Many other potential optimizations are also possible now.

vm: rework stack as a simple slice Double-linked list is quite expensive to manage especially given that it requires microallocations for each Element. It can be replaced by simple slice which is much more effective for simple push/pop operations that are very typical in a VM. I've worried a little about more complex operations like XDROP/1024 or REVERSEN/1024 because these require copying quite substantial number of elements, but turns out these work fine too. At the moment Element is kept as a convenient wrapper for Bytes/BigInt/Bool/etc methods, but it can be changed in future. Many other potential optimizations are also possible now.

vm: rework stack as a simple slice Double-linked list is quite expensive to manage especially given that it requires microallocations for each Element. It can be replaced by simple slice which is much more effective for simple push/pop operations that are very typical in a VM. I've worried a little about more complex operations like XDROP/1024 or REVERSEN/1024 because these require copying quite substantial number of elements, but turns out these work fine too. At the moment Element is kept as a convenient wrapper for Bytes/BigInt/Bool/etc methods, but it can be changed in future. Many other potential optimizations are also possible now.

vm: rework stack as a simple slice Double-linked list is quite expensive to manage especially given that it requires microallocations for each Element. It can be replaced by simple slice which is much more effective for simple push/pop operations that are very typical in a VM. I've worried a little about more complex operations like XDROP/1024 or REVERSEN/1024 because these require copying quite substantial number of elements, but turns out these work fine too. At the moment Element is kept as a convenient wrapper for Bytes/BigInt/Bool/etc methods, but it can be changed in future. Many other potential optimizations are also possible now.

vm: rework stack as a simple slice Double-linked list is quite expensive to manage especially given that it requires microallocations for each Element. It can be replaced by simple slice which is much more effective for simple push/pop operations that are very typical in a VM. I've worried a little about more complex operations like XDROP/1024 or REVERSEN/1024 because these require copying quite substantial number of elements, but turns out these work fine too. At the moment Element is kept as a convenient wrapper for Bytes/BigInt/Bool/etc methods, but it can be changed in future. Many other potential optimizations are also possible now.

vm: rework stack as a simple slice Double-linked list is quite expensive to manage especially given that it requires microallocations for each Element. It can be replaced by simple slice which is much more effective for simple push/pop operations that are very typical in a VM. I've worried a little about more complex operations like XDROP/1024 or REVERSEN/1024 because these require copying quite substantial number of elements, but turns out these work fine too. At the moment Element is kept as a convenient wrapper for Bytes/BigInt/Bool/etc methods, but it can be changed in future. Many other potential optimizations are also possible now.

vm: rework stack as a simple slice Double-linked list is quite expensive to manage especially given that it requires microallocations for each Element. It can be replaced by simple slice which is much more effective for simple push/pop operations that are very typical in a VM. I've worried a little about more complex operations like XDROP/1024 or REVERSEN/1024 because these require copying quite substantial number of elements, but turns out these work fine too. At the moment Element is kept as a convenient wrapper for Bytes/BigInt/Bool/etc methods, but it can be changed in future. Many other potential optimizations are also possible now.

vm: rework stack as a simple slice Double-linked list is quite expensive to manage especially given that it requires microallocations for each Element. It can be replaced by simple slice which is much more effective for simple push/pop operations that are very typical in a VM. I've worried a little about more complex operations like XDROP/1024 or REVERSEN/1024 because these require copying quite substantial number of elements, but turns out these work fine too. At the moment Element is kept as a convenient wrapper for Bytes/BigInt/Bool/etc methods, but it can be changed in future. Many other potential optimizations are also possible now.

vm: rework stack as a simple slice Double-linked list is quite expensive to manage especially given that it requires microallocations for each Element. It can be replaced by simple slice which is much more effective for simple push/pop operations that are very typical in a VM. I've worried a little about more complex operations like XDROP/1024 or REVERSEN/1024 because these require copying quite substantial number of elements, but turns out these work fine too. At the moment Element is kept as a convenient wrapper for Bytes/BigInt/Bool/etc methods, but it can be changed in future. Many other potential optimizations are also possible now.
