( #3333=superdoc: print w/ replies, xml ) Need Help??
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?
