Could you please explain what does '1 + n-1' mean?
This is your code:
template Is(ARGS...) if(ARGS.length % 2 == 0) {
enum N = ARGS.length/2;
static if(N == 1) enum Is = is(ARGS[0] :
Seems like is expression doesn't support type tuples:
pragma(msg, is(short : int)); // true
enum Test(ARGS...) = is(ARGS[0..2] : ARGS[2..4]);
pragma(msg, is(Test!(int, int, int, int))); // false
pragma(msg, Test!(int, short, int, int)); // false
Is it by design, or just

But it should be not too much hard to implement it your code.
Just use two is(), or use recursion (with splitting in two, and
not 1 + n-1).

I already have one:
template Is(ARGS...) if(ARGS.length % 2 == 0) {

Look for this problem in the digitalmars.D.learn group, because I have
seen this problem recently solved here (I don't remember the solution,
it was easy).

I'd recommend something like this be added to Phobos.
Looks nice. There are many small bits of functionality like that that are
missing still in Phobos and can be added. I suggest you to put that code in a
bugzilla entry (otherwise I can do it myself) with a good unittest{} and
