I read Defining a sub within a sub: OK? with interest, but consider the following 

sub foo {

    my @arra = ('a' .. 'z');
    my @arrb;
    for ( 0 .. ( $#arra - 1) ) {
        bar($_);
    }
    
    bar($#arra);

    sub bar {
        my ($i) = @_;

        push @arrb, $arra[$i];
        
    }

    return \@arrb;
}

The above works, but what all sentiments and principles am I violating here? (besides, of course, Blond highlights with a hint of purple are just "so 2007

Essentially, bar() will never be called from outside foo(), and makes sense only within the context of foo(). In case I shouldn't be doing the above, then how should I rewrite it?
