Hi.
It would be great to be able to reverse usage/definition parts in haskell-way with "where" keyword. Since Python 3 would miss lambda, that would be extremly useful for creating readable sources.
Usage could be something like:
>>> res = [ f(i) for i in objects ] where: >>> def f(x): >>> #do something
or
>>> print words[3], words[5] where: >>> words = input.split()
- defining variables in "where" block would restrict their visibility to one expression
- it's more easy to read sources when you know which part you can skip, compare to
>>> def f(x): >>> #do something >>> res = [ f(i) for i in objects ]
in this case you read definition of "f" before you know something about it usage.
