PHP will also call the autoloader when it encounters the namespace

This will result in a call to the autoloader with arguments (null, "B")
you (and the current implementation's) callback defines 1st argument as
string. Changing it to accept null will be a big BC break you missed.
Maybe an empty string would solve that.
