Was Fatal too complicated, or something? After all, that's core now.

    No.

    Fatal overrides open; overriding I/O functions has been prohibited by coding standards nearly everywhere I've worked.

    Also, the above is very much simplified from the live module I use (NDA and all that, can't be too careful): my actual code calls out to Log::Log4Perl and optionally calls out to Carp's croak or carp functions, falling back to warn if these can't be found.

    AFAIK, Fatal doesn't do those things. Besides, even if I didn't have those requirements, most code I write falls under requirements such that CPAN modules must be used as-installed (no modification): since the functionality I require is so easy to duplicate, better to have it in a module I can actually extend later.

    I've worked places where something like this was the preferred style. The argument went (and I think it's at least vaguely reasonable) that by using a different subroutine you could tell by looking at the code in question whether an exception would be thrown - rather than having to look at the top of the file for the use Fatal. It also had the advantage of breaking at runtime if you forgot to load the 'safe' module - whereas forgetting to load Fatal.pm meant the code continued to 'work'.
