Rule: Do not provide static methods and properties

[lbajsarowicz]

Paamayim Nekudotayim (double collon / static) should not be used in classes (except reference to const).

This seems too strict for me and hard too explain. It is not only required for constants, but also for calls to parent or to grand-parent by class name.

If you want to discourage static methods and static properties, the rule could be "do not provide static methods and properties". This is debatable too, but more clear.

@schmengler 👍
I can agree that your approach is much better than the one I suggested.

Potential restrictions of this rule (to be discussed)

• static methods without side effects
• static methods as named constructors

[schmengler]

For now, accepted in the form of:

no public static and protected static method/field definitions.
