This introduces an ambiguity: how do you parse "f(1,2)"?  Is it the
function f called with 2 arguments or is it f called with one
argument--the tuple (1,2)?  I don't think there's any way to
disambiguate using parens.

This issue doesn't come up in SML (the only other language I know that
uses concatenation for function application) because all functions in
SML take exactly one argument.
