===========
John Nagle suggested consideration of Unicode Technical Standard #39,
[2]_, which discusses security mechanisms for Unicode identifiers.
It's not clear how that can precisely apply to this PEP; possible
consequences are
* warn about characters listed as "restricted" in xidmodifications.txt
* warn about identifiers using mixed scripts
* somehow perform Confusable Detection
In the latter two approaches, it's not clear how precisely the
algorithm should work. For mixed scripts, certain kinds of mixing
should probably allowed - are these the "Common" and "Inherited"
scripts mentioned in section 5? For Confusable Detection, it seems one
needs two identifiers to compare them for confusion - is it possible
to somehow apply it to a single identifier only, and warn?
