Feel guilty to ask a seemingly babyish question but, either due to bad luck, drowsiness or sheer sloth, I couldn't seem to be able to locate documentation concerning something like $p'a = $a, which I came across in a Perl script I read off the Web. So, I tried that syntax out on a script in attempt to figure things out myself: 
#! /usr/local/bin/perl -w
use strict ;
# ----------------------------------------------------------
my $a = "this\n";
sub this {$p'a  = $a;       print $p::a;}
sub that {$p::a = "that\n"; print $p'a;}
sub more {$p::a = "more\n"; print $a;}
this();                                 # print "this"
that();                                 # print "that"
more();                                 # print "this"
print $p'a;                             # print "more"
print $p::a;                            # print "more"
print $a;                               # print "this"
# ----------------------------------------------------------
sub a'this {$p'u'a = "mooo\n"; print $p::u::a;}
a::this();                              # print "mooo"
print $p'u'a;                           # print "mooo"
# ----------------------------------------------------------
sub a::that {$p't'u = "wwoo\n"; return sub{print $p't'u}}
$a'that = a'that();
$a'that->();                            # print "wwoo"
$a'that = a'that();
$p::t::u = "booo\n";
$a'that->();                            # print "booo"

Does that mean $p'a is a namespace thing? I don't quite comprehend what scope $p'a is. Is it the same thing as $package::var_or_func?

Thanks. This has been a resourceful community here.
