Normalize: method names

[homersimpsons]

function names are correctly normalized but method names are not:

<?php

class A {
  public static function a() {} // <-- This does not get normalized
}
A::a(); // <-- This does not get normalized

Hello. Thanks for opening an issue on Exercism. We are currently in a phase of our journey where we have paused community contributions to allow us to take a breather and redesign our community model. You can learn more in this blog post. As such, all issues and PRs in this repository are being automatically closed.

That doesn't mean we're not interested in your ideas, or that if you're stuck on something we don't want to help. The best place to discuss things is with our community on the Exercism Community Forum. You can use this link to copy this into a new topic there.
