I have a question about getting in and out of subs nicely, especially when calls/returns to subs get numerous or complicated. I'm not sure if it's a question of style or function.

A couple of scenarios. In #1 I don't really wish to return to &foo if the condition in &bar is negative. Is just exiting an okay move? 
#--------- 1 ------------
sub foo {
    &bar;
}

sub bar {
     if ($negative) {
        exit();
    }
    return();
}

or, for the sake or purity, do I need to return to &foo and then return out of &foo?
And next, what might be an obvious question, what is the difference between the typical call to &bar in #1 and the addition of 'goto' in #2? 
#--------- 2 ------------
sub foo {
    goto &bar;
}

or is goto for recursive calls only (as discussed here) or just plain redundant? The goto discussion appears to be saying that using goto to get into a subroutine is not recommended.

Thanks!
