[swift-evolution] [Proposal] Typed throws

[Anton Zhilin]

I’ve created a proposal draft, copy-pasting some parts from David Owens’
proposal.
Here it is <https://gist.github.com/Anton3/3e4081da1adbc6e7a7f377987985c289>
.

I had to make one addition, which hasn’t been discussed yet. Look at Multiple
throwing calls
<https://gist.github.com/Anton3/3e4081da1adbc6e7a7f377987985c289#multiple-throwing-calls-in-one-do-block>
section. Is this feature controversal, or it’s fine to keep in the
proposal? Is it feasible from implementation point of view?
