I haven't watched the video yet, but in general I think we need 
some form of error handling that more or less have the same 
semantics as the existing one. There are other ways to implement 
what looks like exception. Just look at the error handling in 
Swift, Zig and the proposal for C++ [1]. I think without any form 
of language support and syntax sugar, error handling is going to 
be a pain.
