What about the fp egg--which uses silex to generate scheme code from
a lexer spec--and links it directly into the resulting binary?

Note that this scheme code (fp.l.scm) contains not only tables generated
by silex, but also a verbatim chunk of 1,120 lines of code from silex.scm.

Does this mean fp is now GPL?
