in reply to return eval { die() } idiom

So the callers do something like the following? 
myfunc() or print "something bad in myfunc $@\n";

Instead of: 
eval { myfunc() } or print "something bad in myfunc $@\n";

I haven't seen this in Perl, that I recall.

It might make sense sometimes, but I suspect that with 2 or more levels of calling functions you end up doing a whole lot of re-die-ing.

Interesting anyway.

    Personally, I do something like: 
    sub x {
    # stuff
    eval {
        # eval-ed stuff
    }; if ($@) {
        die $@ unless UNIVERSAL::isa($@, 'ErrorOrSignalThatICanHandleH
+ere');

        # Handle the error/signal types I can handle here however I se
+e fit
    };

    return 1;
}

    Of course, this assumes a library of error and signal classes, but, then again, if you're using eval-die as a throw-catch mechanism, you would have those, right?
