Lean.ParserDescr
`decide` attempts to prove the main goal (with target type `p`) by synthesizing an instance of `Decidable p` and then reducing that instance to evaluate the truth value of `p`. If it reduces to `isTrue h`, then `h` is a proof of `p` that closes the goal. The target is not allowed to contain local variables or metavari...
