Python has had closures for years.  What kind of scoping did you desire?

If it returns None, it probably changes the content of an object.

You can certainly do your programming in a functional style with Python.

Refuse the temptation to guess.  As many people want to keep the 
newlines as not (it disambiguates the case of end of file and blank
