changecom(`') will treat all sequences as
comments, and thus not do any m4 processing of that portion of the text.

What I would like to do is only have m4 process certain sections
won't exist, because it is a git symlink to the gnulib
submodule, but since you are insisting on a CVS mirror checkout instead,
which doesn't understand git symlinks, that explains why it doesn't
exist for you.

built bleeding edge m4.git (which will someday become m4 2.0),
you can use the changesyntax() builtin to do all that changeword was
doing, and more, and without the speed penalty. But that means relying
on unreleased software, which is subject to change.

At which point, adding in your double-quoted comma would look like:
define(`from_states', `foreachq(`y', `$@', `y`, '')')
Hmmm, what happened to State1? I know I'll need to do a counter or something to
eventually not add an extra comma, but now it seems the $@ isn't right.
Your problem is that because you were underquoting arguments, m4 started
treating the comma as an argument separator, rather than as a literal
string, so you ended up calling statemachine() with (way) more than the
intended 4 arguments.

ows selecting different
regex flavors (m4 1.4.x defaulted to emacs flavor, which lacks
RE_CHAR_CLASSES, but the goal is to allow the posix flavor which
includes RE_CHAR_CLASSES). Until then, unfortunately, the best I can
suggest is to instead write your regexp as `^[a-zA-Z]*$'; this has no
loss in
