[IronPython] Old print syntax as option on IronPython 3

This already exists in 2.x because you can do from __future__ import print_function (which gives you the 2.x behavior on 3.x). The tokenizer just stops yielding out print as a keyword when that's used and instead always returns a name token. I would guess that CPython does something similar in their 2.x branch.
Personally I would suggest first getting this change into CPython 3.x if you really thought it was valuable (maybe a from past import print_statement). I don't think it would be that helpful in translating scripts if IronPython was the only one to have it. Plus print as a function is probably one of the easiest things to move over to and I'm guessing 2to3 translates it w/o any issues.

Subject: [IronPython] Old print syntax as option on IronPython 3
I just saw that Boo supports both print as a function and as a statement.
So I had the Idea of adding an language option to IronPython which allows both syntaxes (and probably emitting a warning when using the old one). This could help in the transition of old scripts to IronPython 3.
I know that the cPython parser does not allow that (using the same word as keyword and identifier), but maybe the IronPython parser is flexible enough to allow both usages?
Just a weird, heretical suggestion, feel free to ignore my mail. :)
