I'm not sure what you mean by "standard object oriented languages". I 
didn't know there was such a thing. There are "popular" OO languages 
(by usage, by interest in the academic community, by marketing 
dollars spent, by magazine space, etc.).

There has been ongoing discussion about metaclasses over on 
comp.lang.smalltalk. And on the Squeak list, Alan Kay has expressed 
doubts about whether metaclasses were a good idea, given the 
difficulty of supporting them in the environment.

At least in Smalltalk, metaclasses do a few things:

* provide a namespace for otherwise global "loose" methods (especially 
constructors)
* provide a namespace for otherwise global variables
* hold class metadata (shape of instance variables, organization for 
browsers...)
* hold compiled methods
* hold selectors and their mapping to compiled methods
* hold a reference to the superclass
(am I missing anything?)

All of these could be (and have been) done by separate reflection and 
namespace mechanisms without requiring metaclasses.

For instance, one could use prototypes for constructor behavior. And 
separate "mirror" objects for reflection. These two are what the Self 
language did; Self did away with classes altogether.

After all, classes are not essential for object-oriented programming. 
Though they've been a comfortable concept in many languages, all you 
really need for OO is objects. Inheritance, classes as objects, etc. 
aren't required.
