Are .pyc's incompatible across versions or did the bytecode spec
remain the same?
In any case, I would expect the 2.0 interpreter to be able to read
1.5.2 bytecode. If the modules are compatible with different versions,
then it must not use any new features not found in all versions. What
I'm getting at is the 1.5 interpreter could be used to byte-compile
the source and then both interpreters use the 1.5-generated bytecode.
(Does anyone know where the bytecode format is documented? I am
interested in understanding how bytecode works and is designed.)
