It's not a problem. The { m1 m2 m3 } syntax is used for repeat alternatives
already, and the meaning is very clear: Each music expression between the
outer { } is a separate argument. Note also that the tupletSequence function
would be implemented entirely in Scheme, the parser would not be modified.
