fcall legal in scanner?

[Adrian Thurston]

Hi Carlos,

I'm glad you like Ragel. I've been working on it for a while now and it's 
nice to hear I'm headed in the right direction.

It sounds like a bug. fcall is supposed to work in actions associated with 
entire patterns (the lex style actions) but they are illegal in the the 
transition/state based embeddings and Ragel is supposed to emit an error. 
Could you post or send me some code which exhibits the problem?

Cheers,
  Adrian
