Actually, better not to export at all:

in MyModule.pm:

package MyModule; sub new { bless {}, shift } sub foo { "do some foo stuff" } 1;
and in the calling code:
use MyModule; my $o = new MyModule; $o->foo();
$o is an object. It can have data, but in this case, it is just a way to tell perl where to find the subroutine foo(). This means you could have several different modules, each with a routine named 'foo;, and by using the object each module returns (customarily) from the call to new(), you can tell them apart. Whereas if you have the misfortune to use 2 modules that both export foo into your namespace, who knows what happens?
