First, Perl doesn't distinguish between names like "new" and "getInstance", so there's no language reason to prefer one.

If your client code has a design reason to know it's dealing with a singleton, you might have a stylistic incentive to use different names, otherwise, make it transparent.

The most elegant way I know of applying singletonhood to a class (if you don't mind introducing new tech) is with the Aspect module. All your code remains the same; you just say

  use Aspect::Singleton;

  aspect Singleton => 'Foo::new';

at the top of your class, and that's it.
