 - Allow customization in ways that most users do not care about (abstraction without cost).
 - Allow generalizing impls without breaking inference.

 Defaults may be set for type parameters in in traits, impls, struct and enum definitions and also methods and fns. They may not be set in `type` aliases. They also may not be set in methods and associated fns of trait impls, such defaults can only be set in the trait declaration. As per RFC 213, parameters with defaults must be trailing and may not be forward declared.
 
-The behaviour of omited parameters in partially supplied parameter lists is as per RFC 213, they are inferred as if filled in with `_`. This is relevant to this [postponed RFC](https://github.com/rust-lang/rfcs/pull/1196) that suggests extending that behaviour to non-defaulted parameters.
