Currently, the lexer consumes the number/number pattern as the token 
FRACTION.  And FRACTION gets used in a few places within the parser 
proper.  (Duration scaling is one example.)  Perhaps the lexer is too 
greedy and should not attempt to tokenize the fraction.  Deferring the 
work to the parser could enable more generalized fraction-like 
constructs such as number/duration, but I am unsure the cost.

David, do you know any reasons why FRACTION is a token and not a parser 
rule?
