I also recently implemented such functions and had planned to try to
clean them up, but haven't gotten around to dealing with lots of the
details, several of which you mentioned in your email.  If you're
interested in seeing what I've got (not documented well),
http://www.astro.princeton.edu/~eford/math/ has some files.

They include some tempaltes for dealing with inifite sequences,
infinite series, and continued fractions, which could be used quite
generally.  A also made a template for manipulating numbers by using
their log that was useful for gamma and beta functions.  I've only
implemented log gamma, gamma, log beta, beta, incomplete beta.  

BTW- Although some code is derived from that of Paul Godfrey, I got
his permission to do whatever with my code, so there shouldn't be
problems with boost and licensing should you want to use any of it.
