/// The `proc_macro_derive_resolution_fallback` lint detects proc macro
/// derives using inaccessible names from parent modules.
///
/// ### Example
///
/// ```rust,ignore (proc-macro)
/// // foo.rs
/// #![crate_type = "proc-macro"]
///
/// extern crate proc_macro;
///
/// use proc_macro::*;
///
/// #[proc_macro_derive(Foo)]
/// pub fn foo1(a: TokenStream) -> TokenStream {
/// drop(a);
/// "mod __bar { static mut BAR: Option<Something> = None; }".parse().unwrap()
/// }
/// ```
///
/// ```rust,ignore (needs-dependency)
/// // bar.rs
/// #[macro_use]
/// extern crate foo;
///
/// struct Something;
///
/// #[derive(Foo)]
/// struct Another;
///
/// fn main() {}
/// ```
///
/// This will produce:
///
/// ```text
/// warning: cannot find type `Something` in this scope
/// --> src/main.rs:8:10
/// |
/// 8 | #[derive(Foo)]
/// | ^^^ names from parent modules are not accessible without an explicit import
/// |
/// = note: `#[warn(proc_macro_derive_resolution_fallback)]` on by default
/// = warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
/// = note: for more information, see issue #50504 <https://github.com/rust-lang/rust/issues/50504>
/// ```
///
/// ### Explanation
///
/// If a proc-macro generates a module, the compiler unintentionally
/// allowed items in that module to refer to items in the crate root
/// without importing them. This is a [future-incompatible] lint to
/// transition this to a hard error in the future. See [issue #50504] for
/// more details.

### Configurability
rust-analyzer strives to be as configurable as possible while offering reasonable defaults where no configuration exists yet.
The rule of thumb is to enable most features by default unless they are buggy or degrade performance too much.
There will always be features that some people find more annoying than helpful, so giving the users the ability to tweak or disable these is a big part of offering a good user experience.
Enabling them by default is a matter of discoverability, as many users end up don't know about some features even though they are presented in the manual.
Mind the code--architecture gap: at the moment, we are using fewer feature flags than we really should.
