ly:moment<=? ??

[Simon Albrecht]

Hello,

while getting to terms with the accidentalStyle code I found that it 
would be useful (currently only for dodecaphonic-no-repeat-rule, 
scm/music-functions.scm:line 1682f.) to have a ly:moment<=? Scheme 
predicate function. It’s easy to do in Scheme:

(define (ly:moment<=? a b)
 (or (equal? a b)
  (ly:moment<? a b)))

but I see that the ly:moment<? procedure is defined in 
lily/moment-scheme.cc.
Do you think it’s worth it to generally provide such a procedure? Or 
just define it locally in music-functions.scm?

Yours, Simon
