That's what I tried at first.  It makes sense, at least to me.  Eventually I
created a function and a macro, both with the same equation.  Not ideal, but
workable in my case.

No, it gave me an error.  I don't have the code here, so I can't tell what
error it was, but once I saw that, I began to wonder what eval_pattern() was
for in the first place, since it wasn't for that.

Anyway, problem (mostly) solved (see above), so it's no big deal.
