At the risk of incurring the wrath of the religious language police, 
one of the few things I miss from perl in python is the -w switch: it 
puts perl in a somewhat paranoid mode where it gives you warnings 
about all sorts of legal but subtle or potentially dangerous 
situations. You can ignore them or not use it, but it often opens 
your eyes to something you didn't even realize you were doing. It can 
be quite a time saver (it's a bit like gcc's -Wall switch).

I honestly don't see any reason for something like that not to be 
included in python (other than perhaps 'if perl has it it can't be 
good' :)
