You are just playing with words.
Remember, Perl derives from English, as much as from other languages. die
means "fatal error. Stop the program". $SIG{__DIE__} is documented that the
original intention was just to have it happen before the program exited because
of a fatal error.
Just because there is a method, eval, that can be used to trap fatal errors
doesn't mean that they shouldn't be called fatal, or shouldn't be called
errors.
And just because there is a method that can be used to trap fatal errors
doesn't mean that it should be used for non-fatal errors. If you want to do
that, you should invent one, like RFC 119 does.
