    Unhappy template params in nested template class as a template param in a typedef

    Is this possible in any compiler at all? MSVC compiler keeps throwing INTERNAL COMPILER ERRORS at me and i'm getting mad
    Code:
    template <class xA>class xB{
	typedef xA::xC<int> E;
};
    I've reduced the code to this, it won't throw a ICE but ít says syntax error at < in the typedef
    Use
    writing software in C++ is like driving rivets into steel beam with a toothpick.
    writing haskell makes your life easier:
    reverse (p (6*9)) where p x|x==0=""|True=chr (48+z): p y where (y,z)=divMod x 13
    To throw away OOP for low level languages is myopia, to keep OOP is hyperopia. To throw away OOP for a high level language is insight.

    What are you trying to instantiate it with?

    No instantion yet, you would go insane if you tried to understand what i'm using it for, it just doesn't compile as it is!

    That code segment compiles fine on VC7 (back home now )

    keda: we already noticed that
    template<class A>
    class CWeird {
    A::B var;
    };
    doesn't work, so why should this?

    It does work, it's the template class member that doesn't, althought it's ANSI standardized
