Rust's compiler team has been working on a long-term project to

rewrite the trait solver - the part of the compiler that determines which
concrete function should be called when a programmer uses a trait method that is
implemented for multiple types. The rewrite is intended to simplify
future changes to the trait system, fix a handful of tricky soundness bugs, and
provide faster compile times. It's also nearly finished, with a relatively
small number of remaining blocking bugs.
