<p>Just a side note without reading all the stuff going on here.</p>
<p>As much as I would love to have some type safety error handling, I do believe it should be optional in first place. </p>
<p>Image some scenario like this:</p>
<pre><code class="swift">func foo() throws AError {}
func boo() throws BError {}
func zoo() throws CError {}
// We also need some design to handle all errors at once:
func handle() rethrows AError & BError & CError -> ReturnType {}
// As you can imagine the line might become really long and ugly looking
// Merging with existential syntax or typealias?
func handle() rethrows Any<AError, BError, CError> -> ReturnType {}
typealias ABCError = AError & BError & CError
func handle() rethrows ABCError -> ReturnType {}
// But sometime you don't really care which error type might be thrown and your API handles it with some other convention (docs?)
func handle() rethrows -> ReturnType {
try foo()
try boo()
try zoo()
return ReturnType()
}
</code></pre>
<p>A mix of a type safe and the current error handling mechanism would be great, but not just the type safe (except we’ll get <code>AnyError</code>, where just <code>re-/throws</code> might be a shorthand form for <code>re-/throws AnyError</code>).</p></body></html>
