[plt-scheme] Penalties of ->r over -> ?

If I understand the contract docs correctly, ->r is at least as expressive
as -> .

My question: is there any penalty (performance or otherwise) associated
with using ->r where -> would suffice?

(Rationale: the additional names are useful for documentation purposes.)
