@wadetregaskis Regard your first post, I think that in [another thread](https://forums.swift.org/t/starting-to-implement-variadic-generics/21159) there was a discussion about the variadic-are-tuples argument. It seems to me that there is desire (and advantage) to keep built-in tuples and this new concept of "variadic-tuple" separated. What you suggest I briefly mentioned in the `#head, #tail, #length, #reduce, #ifempty` section of the latest version of the document. The problem I mention there (conflict between the built-in Collection methods of the variadic tuple and members with the same name on the common supertype) obviously only occurs if we have the magic `.` syntax access, which you suggest to remove. I have not explored a design in which variadic tuples are only `Collection`s and nothing else, it might be interesting to reason about. About your second post, personally I think that the gains we might have using glob syntax are not worth the implementation required, especially because I cannot find (but that's just me) a reason to limit the number of variadic parameters in a specified range. The `*` vs `+` to indicate `0...` or `1...` is interesting, but I'm not sure if a single character really stands up to indicate what's happening (variadic generic plus specification on the minimum number of parameters required). Maybe if this is a real problem while designing APIs we should find another solution. Sure your suggestions may be worth the addition in the `Alternative Considered` section!
