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.
