🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Upvars do not get their own node-id. Instead, we use the pair of the original var id (that is, the root variable that is referenced by the upvar) and the id of the closure expression.
