I just looked at this (although I used globals() instead of vars(), to
guarantee I got the module-level variables).
Using the code above I get
RuntimeError: dictionary changed size during iteration
Why that is, I have no idea, but changing the code to use the standard
dictionary iterator 'items()' instead of the new, apparently wacky,
'iteritems()' works perfectly.
for k,v in globals().items():
print "%s = %s" % (k, v)
I haven't bothered to track down why this is, but I did want to note
it.
