Re: [Python-ideas] More power in list comprehensions with the 'as' keyword

A solution could be this:

[stripped for l in text.split('\n') with l.strip() as stripped if stripped != '']

so that you can keep both values (l and l.strip()) too.

In Haskell this would be (I translate only the list comprehension structure, leaving expressions in Python syntax):

[stripped | l <- text.split('\n'), let stripped = l.strip(), stripped != '']

Python borrowed 2 out of 3 kinds of list comprehension constructs.

so maybe? [stripped for l in text.split('\n') if stripped != '' let stripped = l.strip()] but this would introduce a new keyword.
