Does it treat '[' and 'as' as separate tokens so whitespace can occur between them?

Yes.

Note that the second alternative is likely to break all sorts of auxiliary tools which scan Python source. etags/ctags and python-mode come to mind. Clearly, python-mode is well within our domain, but other syntax coloring tools aren't.

It's a trivial change to disallow the second form - I'm pretty much 50/50 on whether it's a good idea to allow it or not. Probably "There's only one way to do it" should apply. (The change is trivial - in Grammar/Grammar, just replace [NEWLINE] with NEWLINE in the decorators entry).
