The first step is to add `throw` as a function attribute,
The next step will be to make nothrow the default. I have not prepared a DIP for
that yet, but will.
The short rationale is that exceptions being a "pay only if you use them" is a
complete fraud. They're expensive to support, meaning performance programs use
other ways of signalling errors and use nothrow.
