Don't use symbolic references. This will not compile under "use
strict;" or "use strict 'refs';". If you need references, use hard
references:
$name = "ajay";
$class = \$name; # $class is a reference to $name
print "$name\n"; # prints "ajay"
${$class} = "fred"; # modifies $name through reference $class
print "$name\n"; # prints "fred"
see "perldoc perlreftut" for more information on references.
