This brings up a painful point -- the reason I haven't wrote the default is because it was way much easier to write it in Python. Of course, I shouldn't be preaching Python-is-easier-to-write-then-C here, but it pains me Python cannot be written with more Python and less C.
But the C code on how to do it was present in the code you deleted from ceval.c!
A while ago we started talking about the mini-interpreter idea, which would then freeze Python code into itself, and then it sort of died out. What have become of it?
