Thanks! You left out some details but I think I see - an example
predicate might be "cmp(a.byGrapheme, b.byGrapheme)" and by the
looks of it, that code works in D today.
(However, "cmp(a, b)" would default to code points today, which
is surprising to almost everyone, and that's more what this
thread is about).
