I tend to use the class system to ameliorate the annoying limitations of 
OCaml records. You know, no overloaded field labels, functions can't be 
polymorphic over a set of labels, that kind of thing. I'd be thrilled if 
I could have all of this stuff in a record system and get pattern matching 
back.

In addition to the O'Reilly book and Xavier's talk slides, take a gander at 
Didier Remy's APPSEM notes, where he discusses this issue in detail, and 
provides pointers to a symbolic algebra program which uses modules and 
classes together.
