If we had generalized slicing, would the proposed library function offer
anything superior to `std::make_tuple([I1:I2]product_type...)`?

(Generalized slicing would work both on *any* product type, as well as
on parameter packs, so in at least that sense, it is superior to a
library function that operates only on std::tuple.)
