Is it safe to have 1 letter class names in PHP, e.g A, B, C

Question

Is it safe to have single letter class names like A, B, P, etc?

Answer 1

Why should it be unsafe? You may use them, if you want. It only is discouraged, because single char class names aren't very descriptive...

Maybe you want to give the class a normal name but let the user import it with a short alias?

use Some\Long\But\Descriptive\Classname as A;
