Problem is, there are things you cannot do without
exec/eval: for instance look at the implementation of
my own decorator module, which uses eval to
guarantee a good signature for the decorated function.
Probably it could be done without exec, with
bytecode hacks, but I regard fiddling with bytecodes
as something worse than exec itself. I am not
sure if in Python 3.0 the signature object is
powerful enough to do the job, I never had to
time to check how it works.
