IDENTIFIER

IDENTIFIER

[Brian May]

Is it possible to relax the definition of IDENTIFIER:

{letter}({letter}|{digit}|_)*   { return(IDENTIFIER); }

?

For the work I am doing, I need a way to seperate words
and phrases seperately.

For instance dpkg_postinst/oav_update.

Any one symbol would be OK, but suggested ones include ~!@%&-=/

(or all of them, but I haven't considered if this will cause problems
elsewhere; for instance : probably should not be used, it is used in
allow statements).

~ is already taken to mean a logical not.

Good point.

Better make that list: !@%&-=/

Second thoughts: None of those characters can appear in M4 macro names,
so maybe this isn't such a good idea...

In fact the current definition seems to be the same as the definition
for M4 names.

Even if I just used this other character in type names, there is the
risk that M4 will get confused and expand the wrong thing.

For now I will simply use the (perhaps more ugly looking) '__' instead.
