Hi Han-Wen,
I assume you're referring to the function in, but I
can hardly say I understand anything to it :-) Do you want this to
replace the use of ly:get-length as a Scheme function?

I was afraid such features might be slower in Scheme than in C++; that
being said, I am not able (yet) to implement anything in C++ on my
own. (in ten years from now, maybe...)

Neil: Debussy suddenly looks a lot easier :-)
