[PATCH] D17778: TypedError for recoverable error handling

[Lang Hames via llvm-commits]

lhames added a comment.

Big readability update:

(1) Main classes / utilities renamed from TypedError -> Error.
(2) Added ErrorHandlerTraits machinery to deduce handler type for handler RTTI checks. This removes the need to wrap handlers in a 'handleTypedError<T>' call.
(3) Rename catch* to handle*.

The new handler idiom is:

  handleErrors(std::move(E),
    [](const CustomErrType &EI) {
      // ...
    },
    [](const CustomErrType2 &EI) {
      //...
    },
    ...);

Otherwise the scheme is unchanged from the original patch.
