 overloading - perl pragma to lexically control overloading

SSYYNNOOPPSSIISS #

     {
         no overloading;
         my $str = "$object"; # doesn't call stringification overload
     }

     # it's lexical, so this stringifies:
     warn "$object";

     # it can be enabled per op
     no overloading qw("");
     warn "$object";

     # and also reenabled
     use overloading;
