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

if (is(X == struct))
{
   ...
}

static if (is(X == struct))
{
    ...
}

ptherwise lots of strnage errors ;)


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))
{
   // ...
}
