Yeah, I have done something similar.  I had it so it would use the class
type to check ranges in development builds, and use actual primative types
in release builds.

You can use floating point types, but you cannot specialize on a floating
point constant like you can with intregal types.  This wasn't a problem for
me as it specified the actual range in the constructor.
