Speaking only for myself, I see mathematical notation as appropriate
for abstractions, and prefer to strengthen TOOWDTI from "preferably"
to "there's *only* one obvious way to do it" in evaluating proposals
to introduce such notation.  This is because mathematical syntax is
deliberately empty of semantics.  Context must determine the
interpretation, or mathematical notation is obfuscation, not
clarification.
