This is a tracking issue for the "match ergonomics using default bindings mode" RFC (rust-lang/rfcs#2005).

Status: Awaiting stabilization PR and docs PR! Mentoring instructions here.

Steps:

• Implement the RFC
  • Initial mentoring instructions can be found here
  • Help guide people to use it via a targeted error message.
• Decide to stabilize
• Adjust documentation (see instructions on forge)
• Stabilization PR (see instructions on forge)
  • Stabilize match_default_bindings #49394

Unresolved questions:

• How to handle the logic around explicit bindings and coercion? Resolve how to handle coercions and the like under default binding modes #44848
• When precisely should constants "autoderef"? resolve how to handle constants and default binding modes #44849
• Reset to by ref mode? somewhat surprising match default binding interaction #46688
