Enumerators are user defined integral types taking discrete, user
defined values. For example:

// Mon=0, Tue=1, Wed=2, Thu=8, Fri=9 Sat=20 Sun=21
enum Days { Mon, Tue, Wed, Thu=8, Fri, Sat=20, Sun};


The above is the type. It does not occupy space the same as int, or a
class does not occupy space by itself. Its objects do:


Days oneday=Wed;


switch(oneday)
{
 case Mon:
// ...
}

What is that _T you are using all the time anyway? It seems to me
something like "boxing" (as it happens in .NET for example).
