The main step to get ContextL to work is to get Closer to MOP to work  
first. I hear that the CLOS MOP support in ECL improved, and my  
understanding of how to make implementations conform better to the  
CLOS MOP specifications improved as well. I only need to find some  
time to spend on this. I currently have an improvement of Closer to  
MOP in the pipeline, as well as another improvement of ContextL.  
Afterwards, I need to decide how to spend my time on either ECL or  
SCL, or both. I'm sorry that I don't have better news for you.


Best,
Pascal
