Re: What Should I learn Before Cocoa?

However, I still look at some of the code in Objective-C and compare it to C++ and wonder why the function calls in Objective C are so dang long. I don't know of another language where you specify the function's variable along with the passing variable.. :)

Some responses:

(a) They aren't function calls, they're message sends. The method invocation that they result in is looked up dynamically at run time.

(b) Functions aren't passed variables, they're passed parameters. Same with message sends. Passing the parameter names is very useful, it really does lead to much more self-documenting code than most other languages.

(c) The keyword-argument message send syntax comes from Smalltalk. Common Lisp also supports optional keyword arguments.
