I think my brainwashing may be complete - I looked at some Obj-C code the other 
day and immediately saw a potential monad.

(for the curious: there's a Maybe monad in Haskell which can be used to string 
together a sequence of operations which may or may not return a result. A 
sequence of Object#try calls would be the equivalent in ruby. This lends itself 
particularly well to a series of possibly-failing setup commands.)
