Lang

Full report

In this week’s meeting, we promoted two RFCs to FCP:

  • RFC 1492 proposes to permit .. notation in patterns as a more general replacement to _, so that one can write a pattern like Foo(x, ..) instead of Foo(x, _, _, _).
  • RFC 1592 is a small amendment that corrects an oversight in the original well-formedness RFC, by making tuples require that all elements except for the last element be Sized (just as structs do).

In addition, RFC 1358 remains in FCP for another week as we discuss the precise interaction between custom alignment and packed structs. It seems that there is a difference in behavior between MSVC and GNU and it’s not entirely clear which behavior to adopt.
