What do you think people will do:
A - handle the exception correctly at the right place and mark
the whole chain of calls as `throws`
B - mark a single function as `nothrow` and catch the Exception
with a dummy handler
B is dangerously easier to do.
Also the statu quo isn't so bad: an unhandled exception crash,
which is an unrecoverable error, as good as an
assertion-in-release. Not handling one is a bug, and it acts like
How many times will D break all code in the future?
