Me too, but I think I figured it out.
The following tidies the specification up a bit, as well as more closely
matching the behaviour of the J parser.
Still room for improvement though!!

<!-- problems/shortcomings
perhaps control should be done as keywords
not sure how to include suffix
primitives other than =: =.
highlight missing single quotes would be nice
parens inside expdef
matched vs unmatched parens coloring
marking matching paren might be nice but how to
do () and not {} and [] -->
