Well it would - the ? operator works on function names, not their
operator equivalents.

Hmm - that sounds like a lot of work!

Well I guess if everyone read and understood the entire documentation
before posting on the newsgroup, 90% of the threads would vanish - but
that would be true of just about all software support newsgroups.

Probably because people don't scan the entire back history of posts,
before asking their question!

I do think Mathematica could usefully exploit more extended characters
as synonyms for operators like @@@ - just as they do for :> etc.

It is important to realise that anyone can understand any expression
involving operators by using Hold and FullForm:

(f @@@ g) // Hold // FullForm
