.apply_to_device ⇒ Object
These ‘apply_to` methods are horrible. They should really be implemented as part of the usual system of constraints that apply to a type and provider pair, but were implemented as a separate shadow system.
We should rip them out in favour of a real constraint pattern around the target device - whatever that looks like - and not have this additional magic here. –daniel 2012-03-08
