Re: [clisp-list] MOP

[Peter D. <pet...@ni...>]

Hi,

Clisp doesn't have a MOP. In theory at least, you should be able to replace 
its CLOS implementation with PCL (Portable Common Loops), which is fairly 
close to the MOP described in Kiczales' book. There is, in fact, a source 
distribution of PCL that includes the low-level routines to apply PCL to 
CLisp. However, it is out of date with Clisp. I have spent some time trying 
to get it to work again, but have not completed this work.
