Too golfy or arcane? (fixed now)
sub map_pairs(&@) {
my $fn = shift;
my $pkg = $main::{caller().'::'};
map {
@{$pkg}{qw(a b)} = \(@_[0,1]);
$fn->(shift, shift);
} (0..$#_/2);
}
package Smarter;
our($a, $b) = qw(orig value);
my @arr = qw(a b c d);
print main::map_pairs {$_[0] = uc($a); print "[$a $_[1]]\n"; $a} @arr;
print "\n";
print "Now @arr\n";
print "\n$a $b\n";
I like being able to avoid sym refs and all the globbage. The interesting thing to note is that I seem to get a magical localization of my variables.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
