Comment #1 on issue 2449 by address@hidden: Redesign stream event class  
representation
http://code.google.com/p/lilypond/issues/detail?id=2449

Ugh, that's really ugly.  Dispatchers internally call ly:make-event-class  
and are, more or less, supposed to be an abstract construct not related to  
layouts, contexts or anything.  So it would appear that the concept of  
non-constant event class relationships involves a serious redesign of a  
_lot_ of things.  This task really gets uglier and uglier.

It is, actually, the existing code that is ugly and hard to change.
