[swift-evolution] [Pitch] Eliminate tuples - unify member access syntax

[Derrick Ho]

Don't remove tuples.
They make it very convenient to pass multiple values around.

Tuples use .0 instead of [0] which prevents any index out of bounds issues
at compile time rather than at run time.

Tuples should not adopt a dictionary style access because dictionaries
imply nil for any key that doesn't exist in the dictionary. Tuples syntax
prevents you from using non-existent keys.
