Local Effects

• local confines a change to a block

• We saw:

        { local *F = \&VeryLongName::SomeFunction;

          F(...);
        }

        { local $| = 1;
          $rc = print $self "";
        }

        { local $/; $code = <$fh> }

• Wouldn't it be nice to be able to do this:

        { local chdir $DIR; 
          ...
        }
        # Old directory is restored here
