That's basically the current state of things. I have wanted to make %f
do more, including evaluation, but I didn't have a good method for
numerical evaluation. Having %f simplify to simpler functions is
sometimes also nice, but sometimes not.
I basically got stuck at these points and haven't done anything with them.
P.S. I'm not the author of the hypergeometric stuff. I just play with it.
