P2165R1 Compatibility between tuple and tuple-like objects (Corentin Jabot)

[inbal2l]

Review summary:
Topics to be addressed in a future revision:

1. A request for additional clarification for the motivation - why does comparing a pair to a tuple desirable.
   The question of defining which types will be supported in more detail was raised.
   Comments include:

• use of T<UT...> as a parameter in the constructors rejects types with non-type template parameters, including std::array.

• Paper should address tuple<int, double> constructible from ptr_tuple<int, double> (will not compile).

  Author's replay: Some of the types were considered and support requires complex additions. I agree this needs to be stated explicitly in the paper.

2. A request to explore in more detail information regarding the implementation experience and expected implications.
   Comments include:

• Is the proposal implementable with backward support (and is it needed).
• Does the implementation pass the existing tests for tuple in a stdlib implementation.

Waiting for next Revision.
