Is there any reason why template typedefs are not allowed? Something like:

template <class T>
typedef T *GeneralPointer;

GeneralPointer<int> iptr;

Trivial example, I know, but there are reasons I would like this.

I would find this convenient as well, but it's easy to get this
functionality in a slightly different way (and perhaps this is the reason
that it isn't supported directly?):

template <class T> struct foo {
    typedef T * GeneralPointer;
};

foo<T>::GeneralPointer iptr;
