So any combination that happens a thousand times in FPC sources warrants 
a language extension? Weird way of reasoning.

So how many of those 910 were nested?

Anyway, IMHO it is exchanging math syntax (sometimes with parenthesis, 
but very general) with very specific semantic syntax.

Yes, occasionally it saves a few parenthesis, but overall the benefits 
are razor thin. And if you lower the threshold this much, where will it  
end?
