It is extra work, though, and any work that can be avoided is nice.  😀

Doing some very light profiling here, a lot of the time is taken up by
skkdic-get-entry, which is just lookup-nested-alist.  My guess is that
if somebody took a look ja-dic-cnv.el, this algorithm could be made
substantially more efficient by using other data structures than an
extremely long nested alist.

But I have really no idea what it's really doing, so it's a bit daunting
to start poking at the code.  And my guess is that's why nobody else
has, either, since not many people currently hacking at Emacs has the
required domain knowledge.

Well, that doesn't sound all that complicated, eh?

(I'm hoping to entice somebody to see this as a fun challenge.  😀)
