This implementtion doesn't use any template specialzation. It works pretty
much like this:

1) Pass expression into a function template;
2) Use VC bugfeature to instantiate a template, something like this:

struct blah<ID>
    typedef T type; // T is known inside the function template

3) return ID through the sizeof();
4) use blah<ID>::type

No specializations, no encoding -- nothing. Compiles in no time at all and
handles anything.
