Why? We have languages with extensible sets of identifiers, and none of
the well-designed ones runs into this problem. It is simply a matter of
specifying the lexis of operators so that they can be distinguished. As
an obvious cheap and ugly way, require all user-defined operators to be
delimited by $...$, or some other character not used elsewhere.
