The only reason to subclass Deduction (with SDeduction) and then

project; but I was hoping for a different way. Thanks.
I think that what you would typically do is either to add:
"-[DeductionLine initWithDependency:]"
// Where Deduction line doesn't know, or care about, what particular
// type of object is being passed, as long as it is either a subclass
of
// Dependency, or it conforms to a specific protocol.
Or something like:
"-[DeductionLine initWithProperty:]"
// Where the caller doesn't know about different Dependency classes,
// and instead specify some type of configuration / context property,
to
// which the DeductionLine responds by instantiating an appropriate
// Dependency subclass.
