You're absolutely right with your analysis, with one > small clarification:
Thanks for taking that on too. I haven't set up module hierarchy yet so I'm not in a position to handle levels, but I have started parsing them and generating the opcodes. Is it sufficient to just use the number of dots as an indication of level? As a side note, I suppose it's sufficient to just *peek* at the stack rather than pop the module and push it again. I'm guessing that's what the Python interpreter is doing. > In theory, I suppose, you could replace the POP_TOP with a STORE_FAST > into "sys", and thus get a two-way import that both grabs the module > and also grabs something out of it.

I'm guessing you mean that would basically optimize: from sys import path import sys It would definitely be a fringe thing to do... -- https://mail.python.org/mailman/listinfo/python-list
