I don't like exceptions because it introduces implicit/opaque/surprise/confusing
execution flow.

...but if I call a function that could fail due to the very nature of what its
doing (e.g. deserialises a configuration from a file), I absolutely the hell do
_not_ want it to handle the error for me. That would be _terrible_.

If you think rust would be improved by removing `?`, please, for your own
benefit, find other people to hang around with, because that is the crazyist
thing I've heard since someone genuinely said "html is one of the harder
programming languages".
