Research direction

Start by reading the discussion in Rust issue 61888 and compare it with the current Rust Reference coverage of traits, impls, and lifetimes. Document that impls may be more general than traits within the intended limits, and clearly identify the early- and late-bound region distinction as a possible area for future change.

Description

A-types

As discussed in https://github.com/rust-lang/rust/issues/61888, the current (and intended) behavior is that impls may be "more general" than traits when it comes to lifetimes -- though within some limits.We should document this behavior as intended, although some of the particular limits -- i.e., the distinction between early- and late-bound regions -- is something that we may want to change.
