Drastically speeds up `isTracingEnabledFor` in the common case, which has evolved from "no options set" to "`Elab.async` and probably some linter options set but no `trace`". ## Breaking changes `Lean.Options` is now an opaque type. The basic but not all of the `KVMap` API has been redefined on top of it.
