Well, here is an example.  Since you won't add variables to macros, I

dnl change quote characters to [ and ] while defining macros
changequote([, ])
dnl change comment character to % (up to the newline)
changecom([%], [
])

define([TextVShift],
       [\property Voice.TextScript \set #'extra-offset = #'(0 . $1)])

dnl use \ as an escape for macros
changesyntax(address@hidden)
\dnl remove quote characters
\changequote(,)
