Hello, Nader!

As for `contributes` attribute, you could override `contribute(self,
data, context)` method in your descendant of `workflows.Step` which by
default simply iterates over all keys in `contributes`.

Either you could use even more flexible approach (which also fits for
`default_steps`): define in your `workflows.Step` descendants methods
`contributes(self)` and `default_steps(self)` (with the conditional
logic you need) and then decorate them with @property.
