2025-06-24	Remove the deprecated `concat_idents!` macro	Trevor Gross	-15/+0
	In [137653], the lang and libs-API teams did a joint FCP to deprecate and eventually remove the long-unstable `concat_idents!` macro. The deprecation is landing in 1.88, so do the removal here (target version 1.90). This macro has been superseded by the more recent `${concat(...)}` metavariable expression language feature, which avoids some of the limitations of `concat_idents!`. The metavar expression is unstably available under the [`macro_metavar_expr_concat`] feature. History is mildly interesting here: `concat_idents!` goes back to 2011 when it was introduced with 513276e595f8 ("Add #concat_idents[] and about the same: let asdf_fdsa = "<.<"; assert(#concat_idents[asd,f_f,dsa] == "<.<"); assert(#ident_to_str[use_mention_distinction] == "use_mention_distinction"); (That test existed from introduction until its removal here.) Closes: https://www.github.com/rust-lang/rust/issues/29599 [137653]: https://www.github.com/rust-lang/rust/pull/137653 [`macro_metavar_expr_concat`]: https://www.github.com/rust-lang/rust/issues/124225
2025-04-24	Deprecate the unstable `concat_idents!`	Trevor Gross	-0/+1
	`concat_idents` has been around unstably for a long time, but there is now a better (but still unstable) way to join identifiers using `${concat(...)}` syntax with `macro_metavar_expr_concat`. This resolves a lot of the problems with `concat_idents` and is on a better track toward stabilization, so there is no need to keep both versions around. `concat_idents!` still has a lot of use in the ecosystem so deprecate it before removing, as discussed in [1].
