Initial Comment:
Python Version: Python 2.4
OS Version: Microsoft Windows XP [Version 5.1.2600]

There may or may not be (according to some people on 
#python on irc.freenode.net) a fault, if you will, in 
the way that Python evaluates dictionaries (in this 
case, globals()).

<titanstar> apparently printing of dicts are optimized 
not to produce the entire output string before 
printing it

This may be an advantage when it comes to processing 
speed and memory management, but when it comes to 
catching errors, this could very well be a problem.

(I am waltz.)

...
<waltz> you think it should print a dict with an error 
in it?
<waltz> ha! caught ya there!
<dash> well, if there's an error, it should break.
<dash> and it did.
<waltz> It shouldn't print AT ALL.
<dash> why not?
<waltz> Because of the ERROR!
...

I'm saying it should raise an abstract exception 
(something like DictError) BEFORE printing, as to 
allow the programmer to handle the error.

Some people don't agree with my argument, but I'll let 
you (the core developers) decide what's best. I just 
thought I should mention this issue, to help improve 
Python to the max!
