Comment #6 on issue 3781 by skirpic...@gmail.com: String printer for factorial/subfactorial shouldn't be a pretty-printer!
http://code.google.com/p/sympy/issues/detail?id=3781

It was  issue 2889.

Sorry, I don't see the discussion.

I agree that "n!" doesn't belong in the str printer. It looks inconsistent.

Well, taking in the account #2 - this looks consistent.

But I'm not sure if this is a good idea. I had an impression that this printer should behave like repr(), e.g. produce a valid Python expression. And, from another side, that sympify() should be a more liberal convertor from a number of notations, not just this one.
