[erlang-questions] Leex - a lexical anaylzer generator, released

[zambal]

Hi Robert,

I have totally no experience with lex or any other tools in this
class,
but out of curiosity I was reading lfe_scan.xrl and was wondering what
these #' #` #; #, and #,@ separator rules are for. Are these just
reserved for later use or are they part of some undocumented syntax?

Thanks,
Vincent

PS Thanks for releasing LFE, it 'slurps' most of my spare time
lately ;-)
