Can someone provide a snippet which, when run, generates a TabError?
I can only seem to get SyntaxError and IndentationError.

Thank you, but I knew the motivations for this
odd behaviour, which can be found as well in, for
example, MetaFont.
Wouldn't it be nice if list.count, called without any arguments,
returned a dict with the list's unique items as keys and their
frequency of occurance as values?
>>> [1,2,1,'a'].count()
{'a': 1, 1: 2, 2: 1}
>>> 'hello world'.count()
{' ': 1, 'e': 1, 'd': 1, 'h': 1, 'l': 3, 'o': 2, 'r': 1, 'w': 1}

def getlength(w): return len(w)
s = map(getlength, [word for ln in lines.split() for word in
ln.splitlines()])
(now s is [4, 2, 1, 5, 2, 5, 2, 5])
