Hi,

I would like to know why the opcode is not optimized. Even for some very simple optimization like constant folding.
For exemple:


line     #  op                           fetch          ext  return  operands

-------------------------------------------------------------------------------

 60     0  ADD                                              ~0      5, 7
        1  ECHO                                                     ~0


which is "echo 5+7;"
