There is also no definition of when a value is computed, which is the 
problem: transitions allow one to see when values are computed in ways 
that could not be determined before with black-box testing.

So either we have to make various transition start stuff explicitly 
undefined, or we have to invalidate a whole class of optimizations that 
avoid computing unused values.
