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.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or How to display code and escape characters are good places to start.
