Not magic, witchcraft of course. Completely different things!
But seriously. My logic was just: there are 7k entries with a nil
value, `map-char-table' does the "funcall func + check for nil" stuff
in c code, whereas the loop does it in lisp code; so *if there's a
difference*, it's probably in favor of map-char-table.
But your test has shown that there's probably no significant difference.
That said, I was merely speculating. If you have any reason whatsoever
to prefer the loop (maybe it's even more robust if the table ever
changes) feel free to push, I'm not particular. :-)
