an
Error to kill the program. And as others have pointed out, you might
want to
log a series of messages. Having std.log throw on the first one makes
it so
that you can't log any others.
Then I guess you'd be well advised to use the function that "logs to the
error log", not the one that "logs to the error log and then throws".
No? I mean you're explaining how a screwdriver is not appropriate for
pounding nails.
As has been repeatedly pointed out, the fatal and critical levels are
different levels than the error level. Also, they cannot be turned off.
Access to those levels should not be coupled with throwing an exception.
Convenience functions to log at those levels and then throw an exception
are perfectly acceptable. They just shouldn't be the only/default
mechanism.
A screwdriver is not appropriate for driving nails, but neither is an
explosive-tipped hammer.
