This is more ore less what I had in mind (specific names not
withstanding). But still remains the question of whether each of these
constructions (uS, uR, etc.) is really useful and whether there should
be others. For instance, would it be worth to support something like
properties (using wctype)? Or a capture that matches one code point
and catures its value?
