Sufficiently common in Emacs (~ 600 instances); I've never seen it
anywhere else as far as I remember. All it does is save some typing at
the expense of confusing people from time to time. Personally, I think
it should not be used.
I believe it is understandable to people used to math and logics, but
the very bad thing about it is that in the context of more normal
English text (like a doc string) it may very well be taken for a
misspelling of "if".
