Research direction

Start with the tuple constructors clause at https://eel.is/c++draft/tuple.cnstr and the variant constructor clause at https://eel.is/c++draft/variant.ctor#1. Check how each currently describes the invented $T_i$ syntax, then update both references to use pack indexing consistently; done means the two clauses no longer rely on that invented notation.

Written by the indexing model from the issue text.

Description

P3-Other

https://eel.is/c++draft/tuple.cnstr and https://eel.is/c++draft/variant.ctor#1 provide an invented syntax $T_i$ to denote the $i^{th}$ type in a pack Types.

This invented syntax is completely unnecessary now that we have pack indexing; we could simply write Types...[i], and probably should do so.
