-# `default_free_fn`
-
-The tracking issue for this feature is: [#73014]
-
-[#73014]: https://github.com/rust-lang/rust/issues/73014
-
-------------------------
-
-Adds a free `default()` function to the `std::default` module.  This function
-just forwards to [`Default::default()`], but may remove repetition of the word
-"default" from the call site.
-
-[`Default::default()`]: ../../std/default/trait.Default.html#tymethod.default
-
-Here is an example:
-
-```rust
-#![feature(default_free_fn)]
-use std::default::default;
-
-#[derive(Default)]
-struct AppConfig {
-    foo: FooConfig,
-    bar: BarConfig,
-}
-
-#[derive(Default)]
-struct FooConfig {
-    foo: i32,
-}
-
-#[derive(Default)]
-struct BarConfig {
-    bar: f32,
-    baz: u8,
-}
-
-fn main() {
-    let options = AppConfig {
-        foo: default(),
-        bar: BarConfig {
-            bar: 10.1,
-            ..default()
-        },
-    };
-}
