[Boost-users] Is there/ was there ever a compile-time rational in boost?

Looking through the news-list I have found some discussion back in 2004 
about a rational_c and a fixed_c class.

Unfortunately the thread is broken up.

The posters seem to use pairs of integers to represent rational numbers 
at compile time, apparently with specializations of MPL meta functions.

Does anybody know what ever became of this?  (I just spent all day 
writing something similar, but probably worse :) )
