This is really annoying.  I had forgotten about it, and it just bit me at
work:

 #!/usr/bin/python

 lambdas = []
 for i in range(3):
     lambdas.append(lambda: i)
 for i in range(3):
     lambdas.append(lambda foo=i: foo)
 for l in lambdas:
     print l()

When you run that, the output is:

 qi6e problems: ./closures.py
 2
 2

 0

Grrr......  How can you not get this right when you design a language?!
