pub const DECL_ONLY_META: &str = "bock_decl_only";Expand description
Metadata key marking a synthesised temp NodeKind::LetBinding as
declare-only: it introduces the binding with no initialiser. The shared
hoist_value_cf desugar emits these; every backend’s let emitter checks
this key and emits the bare declaration (let x; / var x T / Rust deferred
let mut x;) rather than a = <value> initialiser. The carried
bock_air::stubs::Value::Bool is always true.
