Regex with backslash in string?

[el_roachmeister]

I am trying to perform a regex on a string that contains a backslash. I
need the backslash in the string but I want to somehow escape it in the
regex. Can this be done? I have posted the code below which outputs
"Not Matched".

#!/usr/bin/perl

use warnings;
use strict;

my $name = 'John \ 123'; # backslash in name causes problem
my $test = $name;

if ($name =~ /$test/) {print 'Matched';}
else { print 'Not Matched';}

Examples of how to match a backslash are found in perlrequick,
perlretut, and perlre -- or in other words, in every section of
the documentation that deals with regular expressions.

#!/usr/bin/perl

use warnings;
use strict;

I do know how to escape a backslash but I am trying to escape a string
that contains a backslash. Is that possible?
