Back to Limsoon
I started working on the optimisation part. I re-read some of the material about optimisation in Kleisli by Limsoon Wong, and did some preparatory work for the implementation.
I also had to re-organise the module structure, because the original structure was no longer coping very well with the increased size and complexity of the program. Code for the database was in the AST module (because of unhealthy dependencies) and horrible things like that. For now, everything is neatly in it's place, and it should allow clean addition of optimisers.
