Ok. Thanks.

Sorry to bug you, but I tried also the following:

class Step(trellis.Component):
    duration =3D trellis.attr(0)

    def __init__(self, machine):
        self.machine =3D machine
        self.prevs =3D trellis.Set([])

instead of

class Step(trellis.Component):
    prevs =3D trellis.make(trellis.Set)
    duration =3D trellis.attr(0)

    def __init__(self, machine):
        self.machine =3D machine

This also works (that is, I get the same schedule in both cases). Is
there a difference between the two implementations? The second
implementation sets prevs as a class variable, but this does not
appear necessary (telling from implementation 1).
