feature request: polymorphic relationships

[shrugs]

Any ideas for implementing polymorphic relationships?

In active record terms, it'd be expressed like

class Teacher
  has_one :schedule, as: :owner
end

class Student
  has_one :schedule, as: :owner
end

class Schedule
  belongs_to :owner, polymorphic: true
end

but unfortunately this relationship is particularly difficult to express at the moment.

Could you please elaborate more?
