New submission from Alex <alex.gay...@gmail.com>:
Basically whenever you have a LOAD_CONST opcode, follwed by a LOAD_ATTR
you can replace both with a single LOAD_CONST. This optimizes things
like ", ".join or "{} {}".format (in my totally unscientific byte code
hackery it's about a 30% speedup on the loading the function). This can
be done in the peephole optimizer.
I'll try to work up a patch.
