Tight, this would work in the current situation.
However, I would not use this as a general implemenation of 'sub?' for
miniPicoLisp, as it is not equivalent to the other versions.
For the current problem, a simple inline replacement of
(or (= X ",") (= X ".") (= X "?"))
with
(member X '("," "." "?"))
would be the best.
