Okay. Yet another question.
I have a datatype called SoundSample which is just a ForeignPtr to an
actual sound resource.
Playing a resource will in the C library return a handle to the
channel. I use a simliar concept where playing a resource will return
a SamplePlaybackRaw.
The sound resource

I'm kind of surprised no one has yet
System.Mem.performGC?

Another question!
Is there a way to force the garbage collector to kick in?
I''m trying to find out if my finalizer gets called correctly but I
don't know if the garbage collector is run.

This does not work as expected on Complex numbers due to some odd
typechecking hassles apparently associated with abs. How do I get this
to typecheck for both real (e.g. Double) and Complex arguments?
\begin{code}
module Jacobi (sn, cn, dn, sd, cd, nd, cs, ds, ns, sc, dc, nc) where

See the HList library (http://www.cwi.ni/~ralf/HList) and use an HList
constrained by your interface.
