+# Summary
+
+Add `Default`, `IntoIterator` and `ToOwned` trait to the prelude.
+
+# Motivation
+
+Each trait has a distinct motivation:
+
+* For `Default`, the ergonomics have vastly improved now that you can
+  write `MyType::default()` (thanks to UFCS). Thanks to this
+  improvement, it now makes more sense to promote widespread use of
+  the trait.
+
+* For `IntoIterator`, promoting to the prelude will make it feasible
+  to deprecate the inherent `into_iter` methods and directly-exported
+  iterator types, in favor of the trait (which is currently redundant).
+
+* For `ToOwned`, promoting to the prelude would add a uniform,
+  idiomatic way to acquire an owned copy of data (including going from
+  `str` to `String`, for which `Clone` does not work).
+
+# Detailed design
+
+* Add `Default`, `IntoIterator` and `ToOwned` trait to the prelude.
+
+* Deprecate inherent `into_iter` methods.
+
+* Ultimately deprecate module-level `IntoIter` types (e.g. in `vec`);
+  this may want to wait until you can write `Vec<T>::IntoIter` rather
+  than `<Vec<T> as IntoIterator>::IntoIter`.
+
+# Drawbacks
+
+The main downside is that prelude entries eat up some amount of
+namespace (particularly, method namespace). However, these are all
+important, core traits in `std`, meaning that the method names are
+already quite unlikely to be used.
+
+Strictly speaking, a prelude addition is a breaking change, but as
+above, this is highly unlikely to cause actual breakage. In any case,
+it can be landed prior to 1.0.
+
+# Alternatives
+
+None.
+
+# Unresolved questions
+
+The exact timeline of deprecation for `IntoIter` types.
+
+Are there other traits or types that should be promoted before 1.0?
