Hello,

Anybody have any sample Ragel state machines they've developed for lexing, oh, say, D code?  I'm very much a learn-by-example kinda guy. You can show me all the docs you like, but it won't mean nuthin til I see a real working example. =P

I think Ragel employs a fantastic method to define language grammars easily, reliably, and readibly.  I really like the fgoto, fret, fcall instructions...now that's power.

I just recently toyed with the D code generation and found a bug.  D treats the expression `p = (tokend)-1` as a C-style cast of `-1` to a type of `tokend`.  `tokend`, however, was clearly defined as a `char*` variable, so it is not a C-style cast as the compiler assumed it was. Maybe just remove that deprecation check, or rather have it more thoroughly check for truly ambiguous code (i.e. when tokend is actually supposed to be a type).

So, naturally I reported this bug to Adrian and a patch came back within the hour.  Sweeet.
