I'm still inlined to think the method table is a good thing to do:

(a) The performance cases I tried seem implausibly bad -- running
character classification patterns over large fields consisting only of
codepoints over U+07FF.

(b) The method tables seem like a better code organization that
separates the responsibilities of the provider from the calling code.
It's also a requirement (or nearly so) if we want to provide some
pluggability or support multiple library versions.

It would be good to hear from others on these points, though.
