Value members

goes through the whole turn lifecycle

create a new turn and put it on the stack
run the lock phase
the turn knows which reactives will be affected and can do something before anything is really done
- run the admission phase
executes the user defined admission code
- run the propagation phase
calculate the actual new value of the reactive graph
- run the commit phase
do cleanups on the reactives, make values permanent and so on, the turn is still valid during this phase
- run the observer phase
run registered observers, the turn is no longer valid but the locks are still held.
- run the release phase
this must always run, even in the case that something above fails. it should do cleanup and free any locks to avoid starvation.
- run the party! phase
