c++ - Checking at compile time if specified value is in a range of a type

Question

Is it possible to check this:

template<class IntType,IntType value>
struct X{};

What I mean by this is, is it possible to check that value supplied by user will "fit" into IntType (which can be any of std integer types) type? For example, I would like to detect something like this:

X<char,300> a;//here 300 is out of range and I would like to be able to detect that.

Boost is the right way, but want you really want is what is coming the new C++0x standard: static asserts. Boost already implements it in boost_staticassert.
