Hi,
I am trying to use ragel to validate grammars defined in RFCs, and
when doing a piece of RFC2822, I find this:
comment = '(' (FWS? ccontent)* FWS? ')';
ccontent = ctext | quoted_pair | comment;
As you can see, each one depends on the other. This is illegal in
ragel, right? Or is there a way around it?
