Why can't I instruct Singleton-classes to use protected constructors?
Is this expected behavior or may I file a bug report?

$this. Many people (including me) are already familiar with 'self' and
expect it to refer to the class from within it is called.

Because of PHP's loose character, we cannot force the user to use
the strict signature anyway. And since we have no overloading
support, but var_args, strict checks make not much sense to me.

Don't you see a difference in the role and power of OOP in PHP and

This is not even a "feature". I think it was a bug which some guys

a bug and a feature is very small). Fortunately this bug has been

y one. I don't think there is a reasonable solution for

In my opinion, the engine should allow adding parameters with
default values to the old API. In your example, we should just keep
the status quo. As I said before, I don't see a solution that "fits the
PHP goal"

It would be as easy to trigger errors like
