In the article "Context System macros, part1: general macros" there  
are all sorts of interesting and useful macros. Among these I have  
set my eye on the processing of commalists.
Question: is there a context macro that takes a commalist (either in  
a token register or \the\tokenregister form) that returns a sorted  
commalist (ascending or descending doesnt matter to me for the moment).
If someone will be so kind to point one out to me. A scan through the  
sources didn't bring an obvious candidate to my attention although I  
feel there must be one, but I may overlooking it.
