Tracking issue for "clarified ADT kinds" (RFC 1506)

[nikomatsakis]

Tracking issue for rust-lang/rfcs#1506.

Status:

Fully stabilized.

Stabilized by PR #41145:

• Numeric fields in struct expressions/patterns S { 0: a, 1: b } are not yet stabilized.
  • We've decided to stabilize the existing support, but we're still in need of a PR. If you're interested in contributing, directions for stabilizing this feature can be found here.

Stabilized by PR #36868:

• Lifted restrictions on tuple structs/variants are stabilized, i.e. S{..} can be used with any structs and empty tuple structs are permitted without feature gate.

@rfcbot fcp merge

I propose that we stabilize this feature. There are no known blockers or interactions and it is a relatively minor extension to existing syntax. I would very much welcome the ability to use {} more consistently.

It has been one week since all blocks to the FCP were resolved.

[nikomatsakis]

Entering FCP. Honestly I'm not clear for how long. =) Stabilizations still confuse me a bit.

[nikomatsakis]

The release is coming up, and this has not exactly been a controversial topic, so we've decide to make it official and approve this for stabilization.
