I asked this question some time ago, and David Kastrup was kind enough to put me right.
The problem , as you mentioned, is in the way that numbers are used for durations. Consider the following code: chord = <c e g> chord2= <d f a> c1 \chord2 Should the second element be interpreted as <c e g>2 or <d f a>1? I imagine this would confuse the lexer horribly. No doubt some rules could be written to resolve this, but it would need some recoding. Easier to stick with using quotes.
