[C++-sig] member function template question.

Your example has several layers of complexity. I believe the main trick you
need to know is how to use a cast to tell the compiler what you want. E.g.:
template <typename FloatType>
vec3<FloatType> const& eigenvalues,
FloatType const& tolerance);
(bool(*)(vec3<double> const&, double const&)) is_positive_definite);
This is a bit cumbersome but somehow you have to define which FloatType you
want to use since you are crossing the boundary between compile-time
polymorphism and runtime polymorphism.
If you don't like the casts you can also define thin wrappers. This works for
both "normal" functions and member functions.
I don't know how this is handled by Pyste. Maybe someone else can help?
I am also not an expert on dealing with raw pointers, in particular void* needs
special attention. I think there is something about void* in the FAQ that you
might want to read.
