From current discussions it seems like the goal here is for type and const parameters to be unordered and allow things like
struct Foo<const N: usize, T = u32>(T)andstruct Foo<T, const N: usize = 7>this way.Note: This means that using
min_const_genericsit will not be possible for an adt to have both type defaults and const parameters.closes #70471
