Matthias Krüger 817720c9a9 Rollup merge of #138799 - joboet:extend-tuple, r=Mark-Simulacrum ... core: simplify `Extend` for tuples This is an alternative to https://github.com/rust-lang/rust/pull/137400. The current macro is incredibly complicated and introduces subtle bugs like calling the `extend_one` of the individual collections in backwards order. This PR drastically simplifies the macro by removing recursion and moving the specialization out of the macro. It also fixes the ordering issue described above (I've stolen the test of the new behaviour from https://github.com/rust-lang/rust/pull/137400). Additionally, the 1-tuple is now special-cased to allow taking advantage of the well-optimized `Extend` implementations of the individual collection.		2025-10-12 10:13:12 +02:00
