Yes, passing a hash by reference is the best way in many
situations. You can also, however, pass it as a list:

%foo = ( one => 1, two => 2 );

MyFunction %foo;

sub MyFunction {

  my %h = @example.com;
  ...

}

In some cases, this may be preferred. It is a common trick for
object constructors, for one.
