-# `param_attrs`
-
-The tracking issue for this feature is: [#60406]
-
-[#60406]: https://github.com/rust-lang/rust/issues/60406
-
-Allow attributes in formal function parameter position so external tools and compiler internals can
-take advantage of the additional information that the parameters provide.
-
-Enables finer conditional compilation with `#[cfg(..)]` and linting control of variables. Moreover,
-opens the path to richer DSLs created by users.
-
-------------------------
-
-Example:
-
-```rust
-#![feature(param_attrs)]
-
-fn len(
-  #[cfg(windows)] slice: &[u16],
-  #[cfg(not(windows))] slice: &[u8],
-) -> usize
-{
-  slice.len()
-}
-```
