I'm going to answer the original question, even though I don't quite
understand it:
> Using explicit parenthesization to convey aspects of semantic meaning?
Absolutely not -- for no other reason that it would break potentially a LOT
of code. If there IS some new useful semantics that could be conveyed with
a set of brackets, we're going to need to use another character.
I still don't get what meaning might be called for, but even commonly used
brackets, like [] or {} would be better because I don't think they can be
currently used anywhere in which they have literally no meaning, like ()
does.
