Java has streams and lamda functions, so the paradigms can definitely
co-exist. I'll have a look at the Guile stuff.

Here's a weird one. Using this definition in the c,-octave, I get a
really weird output. Each note in the music drops down an octave. In
the c-octave, it works normally. Using the untagged version of
\repeatCounting doesn't show this issue in either octave.

Any ideas?
