If You agree we can try to define some hypothetic syntax for OOP.

I think that we should try to stay as close as possibe to Obj-C.

Start blathering:

My provocative proposal is to just drop the ";" as line delimeter.

i.e. message sending:

(example taken from http://en.wikipedia.org/wiki/ObjectiveC#Objective-C_2.0)

[obj method:parameter]

Actually I believe that we can change also some structure syntax for match the FB paradigm:

interface classname : superclassname

...

end interface

class classname : superclassname

...

end class

method sqrrt( "root":r as double, "index":j as double) as int

...

end method = result

(I'm not sure about the pseudo-naming syntax).

Also I believe that we should avoid the inline definiton and assignment statement:

Recipient * recipient = [Recipient new];

to:

dim as ^Recipient recipient

recipient = [Recipient new]

end blathering.

Looks like a plan. So, this @interface section (taken from one of my iPhone apps):

@interface SkiMapicViewController : UIViewController <UIScrollViewDelegate> {

UIScrollView *scrollView;

UIImageView *imageView;

NSInteger map;

}

would look like this in FB?

interface SkiMapicViewController : UIViewController <UIScrollViewDelegate>

dim as ^UIScrollView scrollView

dim as ^UIImageView imageView

dim as NSInteger map

end interface

Maybe we could omit the ^ and let the translator auto-insert the necessary * before appropriate instance variables?
