variadic generics (N-ary zip et al)

I believe there were some ideas and snippets here that might give an engineer a head start on that:

Is it possible to create a cartesian product function with parameter packs?

The shape of the function would be func variableCartesianProduct<each T>(input: repeat [each T]) -> [(repeat each T)] The use case here is as input for parameterized tests. I'd like to take lists of possible inputs and produce all combinations of those lists. I've made a few attempts, but I think there are some missing pieces. You could build up recursive tuples, but I can't figure out a way to flatten them. ie you can't do a transformation of an arbitrary tuple shaped like ((String, Int), Flo…
