David> It's not difficult to use shell variables in perl.  For example:

David>   #!/bin/bash

David>   var=foo

David>   perl -e '
David>     my $var = q{'"$foo"'};
David>     print "$foo\n";
David>   '

Or just:

   var="something arbitrarily complex"
   export var

   perl -e '
        $var = $ENV{var};

No fancying quoting required. :)
