Usually `when no ambiguity can arise', no?  Plenty of mathematical
practice rests on imprecision and the expectation that the human reader
will understand what you mean.  Haskell has to be understandable by the
machine (which is less forgiving, but also more reasonable!) as well.

What?  Are you sure of your lexical choice here?

Unless you, say, enjoy having type inference or something.
