Comment (by darchon):

 Yeah... those rules are the only ones I could think of and stay within the
 domain of the original small-step semantics of System FC. Another way to
 go about it is to add an explicit heap to the semantics, and put let-
 bindings to that heap, ala "a natural semantics for lazy evaluation". But
 then you'd have to update all the other rules also.
