[alicebot-developer] ProgramD - predicate cache saving

[Noel Bush]

Hi Albertas,

I am the maintainer of Program D.  I am currently working on a revamp of 
the Program D code, which will be ready very shortly.  I will take a 
look at the issue you've mentioned.  I have also read your posts about 
the unit testing framework with interest, and would be glad to discuss 
integrating that into Program D as well.
