I'm not sure how to do conditional code in the parser. I set your
recommend string to <chapverse> in the scanner and then tried this in
the parser.

BibleReference :
	( "Genesis" | "Gn" | "Gen" ) [<chapverse>] { Transcript show: '[',
'1' asString, ']' } ;

But this results in a Shift/Reduce Conflict. What I'm trying to
accomplish is 'Gen 3' to be recognized as a bible reference and 'Gen
hello' as a string (not an error).
