The line before your quote has
def:<variable>
which I though implied that "def:" has to be followed by a variable.
Would it be clearer if I explicitly said
"The def: operator must be followed by the name of an expansion
variable?" Or maybe it should be
def:<variable-name>
I'll do both of those. That should make it crystal clear.

Yes, those are always tricky. What I do it first to write the regex as I
want it, then escape all \ and $ that are within an expansion, then
escape all \ that are inside "".
