This is a list of some MOPs in current use or under development.
| ABCL/R | ABCL/R is a series of MOPs designed, particularly, for distributed computing. |
| AL1/D | AL1/D has a MOP that provides several different kinds of meta-objects for different kinds of intervention. |
| Apertos | Apertos is a reflective object-oriented operating system. |
| CLOS | The CLOS Metaobject Protocol was the first metaobject protocol designed
as such. It provides control over the way CLOS implements objects, including
object layout, object initialization, slot access, effective method definition,
and generic function invocation. It is fully described in the book
A good discussion of the CLOS MOP is also available in part II of
|
| Tiny CLOS | Tiny CLOS is a very simple CLOS-like language with a simple MOP. It was designed for teaching purposes. Tiny CLOS is written in Scheme; sources are available from our archive. |
| Dylan | Dylan A dynamic object oriented language, with some MOP features,
particularly for introspection.
|
| Dynace | Dynace is a dynamic OO extension of C/C++ with MOP features |
| EuLisp | EuLisp
has a MOP which does some things more cleanly than the CLOS MOP. The MOP
is described in
|
| ILOG TALK | ILOG Talk is a Lisp dialect which MOP is based on EuLisp's |
| Open C++ | Open C++ is a compile time MOP for the C++ language. |
| Smalltalk | Reflective Facilities in Smalltalk-80 is an OOPSLA 89 paper by Foote & Johnson |
| STk | STk is a R4RS Scheme which can access the Tk graphics package. It provides a CLOS-like object system with a MOP. |
