Hi

I didn't read the full thread, so this might not be important.

But please take also the overhead for allocating memory into account, especially with small arrays and hashes.

It's a big difference if a container has already allocated much space and doesn't need to be expanded, like with variables from the outer scope or if it's newly created or if a list is pushed to the stack.

Not that easy like just parsing the optree. :)
