You have two typos there. Corrected version:
enum bool VerifyTuple = is(Types[0] : Object) && VerifyTuple!(Types[1..$]);
But perhaps even nicer:
----------
template VerifyTuple() {
enum bool VerifyTuple = true;
}
template VerifyTuple(T, Ypes...) {
enum bool VerifyTuple = is(T : Object) && VerifyTuple!(Ypes);
}
----------
(Some of you will be able to guess what other language I've programmed in in my time from
this.)
