tests/ui/impl-trait/reachable-private-fn-codegen.rs

//! Regression test for <https://github.com/rust-lang/rust/issues/50865>.
//! When using generics or specifying the type directly, this example
//! codegens `foo` internally. However, when using a private `impl Trait`
//! function which references another private item, `foo` (in this case)
//! wouldn't be codegenned until main.rs used `bar`, as with impl Trait
//! it is not cast to `fn()` automatically to satisfy e.g.
//! `fn foo() -> fn() { ... }`.
