Hm, I think there are similar problems in Python:
--- snip ---
adict = {'foo': 'bar', 'spam': 'ham'}

for key in adict: # has to be adict.keys()
   del adict[key]
--- snap ---

This snippet leads to a RuntimeError but the first item will be gone.

Of course, you may use the "older" syntax in this case. ".keys()" will 
generate the list of keys once in advance, while the upper example will 
call next() each time AFAIK.
