You could do it the non-programmer's way.  Use sly, (see sly.txt, to
this list, contains all.)  If you use ptfilter.sed, it is easy to write
a simple
substitution

@b c,
 could make
 \openbracket c, \closebracket

in the part lilypond-ly2dvi reads, and you can read it that
way too, in lilypond's style, next year even.  There is a working
example in ptfilter.sed.  Ptfilter.sed is automatically
created by sly as an empty file so you have to copy a non
empty version of it into
your working directory.  If you elect not to use it
because you don't like preprocessors, well, type away.  :-)

The really good part is being able to pass numerical values,
say for stem length, \sl5, \sl2.1, @sl8.5  LEn4.7 etc., your
call.  Of course it's much better to use macros that don't
need such a value by passing them straight through without
preprocessing anything.

A .sly file has this format:

pt1 | pt2 | pt3 etc.---
pt1 | pt2 | pt3
etc.

And each is a ready to run lilypond \notes or \lyrics or
whatever if you do no
substitutions.  Sly-tidy will straighten the field
separators for you so it doesn't take iron discipline
to keep it pretty either.
