>>I prefer many things about Python over Perl I have been doing Python a bit now and am of the opposite opinion. Except for CPAN I miss the advanced stuff like Moose (better OO) and extensible syntax. I might be too new to the language. E.g., I don't really get the list comprehension -- it looks like a kludge around the lack of multi line code blocks, so Python can't have nice a map() syntax. But people seems to love the that syntax, so there should be more to it than a kludge? But sure, Python has a minimal and elegant notation; it just changes a bit too slowly. Also, try posting a flame comment like yours about Python in a Python thread; you'd be at minus ten in five minutes and stupid comebacks would be up voted to orbit. The fanaticism makes RoR kids look mature.

List comprehension is one of those things I miss every I use another language. I am not sure what you mean with: it looks like a kludge around the lack of multi line code blocks could you provide and example?

  Don't you know what map is? But you claimed to be an old Perl programmer? I wrote "Python can't have nice a map() syntax", because of its lack of code blocks. And that list comprehensions seems like a one-statement kludge of the map functionality. How could I have been clearer? OK... second attempt to explain this point: :-) List comprehension seems to me like a one statement replacement of a map function (and that one-statement often makes you think of Perl golf.) And a third attempt: :-) It seems to me that list comprehension would never have been implemented -- if Python had added (optional) support for ';' (+ '{'/'}') and hence code blocks. That is because Python would then use map() instead of list comprehensions (like all other scripting languages, lisps, etc). (Also, a side effect of optional ';' support would mean that Python wouldn't be worthless garbage as a bash cmd line tool.) But please enlighten me about use cases not done clearer/better with code blocks? I note that you don't argue about the fan bois point... :-)
