//! Reserved-identifier rejection for procedure names and procedure
//! argument names — the two `.cstack` ident sites `procedure/types.rs`
//! feeds unguarded into `cratestack_macros::shared::ident` at codegen time
//! (`ident(&to_snake_case(&procedure.name))`, `ident(&arg.name)`). Split
//! out of `mod.rs` to keep that file under the crate's ~200-LoC
//! convention; see [`super::reserved_idents::validate_reserved_identifier`]
//! for the shared check itself.
