How do I get the if statement to evaluate the conditional I have placed into $var?

#!/usr/bin/perl -w
use strict;
my $hash_ref2={
   this=>'that',
   some=>'thing',
   another=>'something',
   };
my $hash_ref1={
   this=>'blarney',
   some=>'foo',
   chancy=>'at best',
};
my @a=($hash_ref1,$hash_ref2);
print "this is ".$$hash_ref2{'this'}."\n";
my $var='$$hash_ref{\'this\'} eq \'that\'';
foreach my $hash_ref(@a){
   if($$hash_ref{'this'} eq 'that'){
      print "I only want to see case where: \"this really does equal "
+.$$hash_ref{'this'}."\"\n";
   }
   if("$var"){
      print "this really does equal ".$$hash_ref{'this'}."\n\n";
   }
}
