The foldings do not currently work the way I want them to. This
may be a limitation of the way they are applied rather than the
regexps in use. Nonetheless, the foldings will end on the last
identically indented blank line following an s-expression. Not
ideal perhaps, but it works. Also, the #illegal pattern never
matches an unpaired ( as being illegal. Why?! -- Rob Rix
Ok, hopefully this grammar works better on quoted stuff now. It
may break for fancy macros, but should generally work pretty
smoothly. -- Jacob Rus
I have attempted to get this under control but because of the way folding
and indentation interact in Textmate, I am not sure if it is possible. In the
meantime, I have implemented Python-style folding anchored at newlines.
Additionally, I have made some minor improvements to the numeric constant
highlighting. Next up is square bracket expressions, I guess, but that
should be trivial. -- ozy`

a tiny bit of complexity in our grammar. It is hopefully
not overwhelming complexity.
Note: the first two matches are special cases. quoted
