I agree, but many young developers have C phobia and somehow seem not to be able to grasp C based languages.

I like C but have Obj-C-aversion because "high level" languages that still need header files all over the place just ain't right.

There I agree with you.

Header files are so 70's.

Or they've been spoiled by certain language features and it seems unbearable to go backwards.

Personally I find great that we have a native Ruby compiler, even if it means a static language with Ruby like syntax in the end.

I hope for the day when we have better and more type safe languages for system programming.

Most attempts so far, Modula-* family, Ada, Oberon and so on, failed to catch on, to my dismay.

Still it does not hurt to know some C.

What language features does Ruby have that Objective-C lacks? It's a bit more succinct, perhaps, but when you're calling out to Cocoa all the time, that succinctness is going to get thrown out the window.

Ruby has "yield" which, while possible to replicate in Obj-C, it's not nearly as nice. Also, Ruby can yield arguments, and the block being yielded to is free to ignore those arguments. That's the sort of flexibility that can make Ruby so much more enjoyable to work with in high-level code.

That's a great example, thanks!

I did some looking, and I found a few[1] examples[2] of coroutines in Objective-C, though none of them seemed fully fleshed-out. Even if they were, none were, as you say, nearly as nice as "yield".
