An alternative, what would be compatible with "unsafe host functions" is to pass pointer to the top stack item.

void unary_op(Value* top)
{
    *top = op(*top);
}

This is done.

Right I see in unary_op.

Could also do a similar experiment to evmone in binary_op/comparison_op to only pop one and overwrite the other.

This is already done this way.

Damn, probably had an old code checked out locally when I looked.
