Is there a way to identify if a type is a struct, something like 
isStruct
similar to isArray.

struct X
{
}

isStruct!X == true?

Also, there are isAbstractClass & isFinalClass but want to check 
if type is a class regardless? something like isClass?

Thanks
Pham

Playing the devil's advocate, I think drug meant it as a function 
template constraint. :o)

void foo(X)(X x)
if (is(X == struct))
{
    // ...
}
