Spending too much time on stemcells when they are not critical right now.
Part way though some hefty changes as types can
now belong to an env.. this means all type helper functions should take
env as an arg...heavy shit man, worth saving before I break stuff
Need to work out how I will store external functions
I've got some crufty crap knocking aroudn from the experiments.
One big win is I have had a real go at the types as I was using types
specs in way too many places. Now the objects are used eveywhere and it
means things are more predictable.
Plan for next bit of work
