This is the core of the Ethereum Virtual Machine (EVM or just VM).

NOTES:

1. Stack items are lazily duplicated, so you must never directly change a buffer
from the stack, instead you should `copy` it first.

2. Not all stack items are 32 bytes, so if the operation relies on the stack
item length then you must use `utils.pad(<item>, 32)` first.
