What you are referring to is a utility class.
It only has static members and a private constructor, which should never be
called (even from the class itself).
Your suggestion could be useful, because implementing private empty constructors
is just boilerplate code.
PS. Some people even throw an exception inside the private constructor.

For Relevancy: I do not believe that namespaces solve this problem, as
__autoload does not work with namespaces (and, for obvious reasons,
shouldn't).

Description:
------------
Fairly simple: A developer is allowed to define his/her classes as abstract or final, but not as
static. For continuity's sake, it would be preferable to be able to declare classes as static
as well. This would greatly ease the creation of static function collections/libraries, especially
those included with __autoload().
When a class is declared as abstract, it is a statement at the open that this is an incomplete
member; you can specify any method inside a class to be abstract and the class is effectively
abstract, yet this keyword is allowed in the class declaration.
When a class is declared final, it is a statement at the open that all members are to be considered
final, and that this class should not be extended any further.
By allowing classes to be declared as static, it would follow with allowing "abstract class
foo" in the sense that the keyword reflects the contents of the class, and would follow with
"final class foo" in that it would define a binding construct for all members of the
class.
Whether
a) In a static class, all methods and members are automatically static
-OR-
b) In a static class, all methods and members must be declared static
Is surely not for me to decide -- either is useful, as it either forces me to ensure all members are
static, or it does the legwork for me. As such, I make no suggestion and defer to the wisdom of the
developer(s).
Thank you for your consideration.
