Hi,

I want to test if template argument is of some form like in the
following code. I could define some helper class to do such test. But
I'm wondering if there is any easy to do it with boost? The
type_traits's is_same does not work in this case. I'm wondering if
there could be some generalization of it.

template <T>
void f() {
//For example, I want to test if T is of the
// form of std::complex<S>

}

Thanks,
Peng
