[OT] Is there a real alternative to exceptions ?

[Manu]

There is, we discussed it informally at dconf quite a lot.
It looks like this:
CppCon 2018: Brand & Nash “What Could Possibly Go Wrong?: A Tale of
Expectations and Exceptions” <https://www.youtube.com/watch?v=GC4cp4U2f2E>

At dconf while discussing this strategy, I had personally never heard of
this proposal but the scheme we were discussing in detail at dconf turms
out to be almost exactly what is presented in this lecture... which is a
good sign! It's not new, and other people agree it's an excellent idea.
