i am not a "more monkish Monk", but i did get curious about this behavior of foreach. This is an alias (example modified from _Advanced Perl Programming_ (O'rielly) by Sriram Srinivasan):
$a = 10; # saclar a
@a = (1, 2, 3); # array a
*b = *a; # aliases b to a
$a++; # increments $a :)
$b++; # same as saying $a++
print "$b, $a"; # prints: 12 12
@b = 4; # same as saying $a = 4
as you can see, the aliasing on line 3 makes any manipulation of $b, @b or %b manipulate $a, @a, %a respectively. hope this helps and is not too confusing.
if i'm wrong, tell me :)
