Cocoa

A whole bunch of CCL Cocoa coding involves calls to Objective-C methods. For instance, the following Objective-C code: [cell drawWithFrame: frame inView: view]; will translate into this in CLL: (#/drawWithFrame:inView: cell frame view) Indeed, Objective-C is designed around the record-based model (methods belong to classes), so the cell object receives the drawWithFrame:inView: message via its Smalltalk descendant syntax. On the other hand, the Lisp translation involves a generic function call with the usual funcall syntax. The dispatch occurs on the first argument (the cell), and the rest is actual arguments to the message.
