in reply to (tye)Re: GOTO considered (a necessary) evil?
in thread GOTO considered (a necessary) evil?

there are cases where $@ can give the wrong impression about whether the eval was successful.

Can you give an example of that?

    Sure: 

        sub DESTROY { eval "1" }
    eval 'my $x = bless {}; die "ouch\n"';
    print "($@)\n";

    which prints "()" not "(ouch\n)".
