Re: goto with some arguments

Personally, I think it is far from beautiful, it is also far from obvious what you are trying to do, try this:

if($this_is_not_right) {
    @_ = (error_code => 123, error_msg => 'this is error');
    goto &somewhere;
}
do_something();
return;

sub somewhere {
    my(%params) = @_;

    show_error_page($params{error_code},$params{error_msg});
}

Why do you need the goto? `&somewhere;` is going to do the exact same thing. Personally I agree with derby's comment down the page. The sub `somewhere()` isn't really needed at all, and the `goto` is completely pointless IMHO. Pass the parameters directly to your error handler. Don't get me wrong, there are legitimate uses for `goto` such as in `AUTOLOAD`. I just don't believe this is a legitimate use. Lobster Aliens Are attacking the world!	[reply] [d/l] [select]
