Sometimes it's nice to be able to have groups of variadic
parameters:
template t(T1..., T2...)

t!(a, b, c; d, e, f);
so that a,b,c are for T1 and d,e,f are for T2.
This can be done by making a symbol and breaking up a single
variadic but is messy.
I doubt such a feature will ever get added but who knows...
You can achieve this like so:
----
template Outer(T...) {
template Inner(U...) {
// Do something with T and U
}
}
Outer!(a, b, c).Inner!(d, e, f);
----
You can see an example of it in action here (type tuple
intersection):
