Hello to all. : )
I was reading throught the advanced reg exp chapter
and regular expression references, you mistyped regexp
variable.  I should should $regex not $regexp. See
below:

$ perl foo
(?-xism:(\S+) hacker)
I found a hacker of type Perl
I have a regex!
Reference type is


$ cat foo
my $string = "Just another Perl hacker,";
my $regex = qr/(\S+) hacker/;
print "$regex\n";

if( $string =~ m/$regex/ )
    {
    print "I found a hacker of type $1\n";
    }

print "I have a regex!\n" if $regex->isa( 'Regexp' );
print "Reference type is ", ref( $regexp ), "\n";


ref( $regexp ) should read
ref ($regex )

$ perl foo
(?-xism:(\S+) hacker)
I found a hacker of type Perl
I have a regex!
Reference type is Regexp

I ran foo file on cygwin 
$ uname -a
