This is the only file in the whole LilyPond distribution that needs a C
compiler to compile.  It also makes for a whole lot of trouble.  What it
does can likely be rewritten in Python without much of a performance
impact for the application as a whole.

So rewriting this module in Python proper would be very much desirable.
I think that somebody™ should really do this.

In other words: raise an issue report about this problem, and I think
the suggestion to solve this problem area once and for all by not using
a C module in the first place should be high on the list of desirable
solutions for the issue.
