in reply to Use of "my" after Perl v5.14

Consider this (notably, the difference between $localPrivateVarX and $localPersistentY):

#!/usr/bin/perl

use strict;

my    $GlobalA = 1;

foreach my $notAGlobalB (qw /X Y Z/)
{
    &displayDashedLine();
    my $returnValueFromM = &subM($notAGlobalB);
    print "Return:  \$GlobalA = '$GlobalA', \$notAGlobalB = '$notAGlob
+alB', \$returnValueFromM = '$returnValueFromM'\n";
    my $returnValueFromN = &subN($notAGlobalB);
    print "Return:  \$GlobalA = '$GlobalA', \$notAGlobalB = '$notAGlob
+alB', \$returnValueFromN = '$returnValueFromN'\n";
}
&displayDashedLine();

exit;


sub displayDashedLine
{
    print "----------------------------------------\n";
}


sub subM
{
    my ($parameterM1, @everythingElse) = @_;
    my $localPrivateVarX;
    if (!defined $localPrivateVarX)
    {
        $localPrivateVarX = 0;
    }
    $localPrivateVarX++;
    print "  SubM:  \$GlobalA = '$GlobalA', \$parameterM1 = '$paramete
+rM1', \$localPrivateVarX = '$localPrivateVarX'\n";

    return;
}


{
    my $localPersistentY;

    sub subN
    {
        my ($parameterN1, @everythingElse) = @_;
        if (!defined $localPersistentY)
        {
            $localPersistentY = 0;
        }
        $localPersistentY++;
        print "  SubN:  \$GlobalA = '$GlobalA', \$parameterN1 = '$para
+meterN1', \$localPersistentY = '$localPersistentY'\n";

        return;
    }
}

exit;
