extern (Objective_C)
As Simen said, we already have extern (C++). But I can absolutely change
this if people wants to.
Regarding this syntax:
void insertItem(ObjcObject object, NSInteger value)
[insertItemWithObjectValue:atIndex:];
Is it possible and good to replace it with some UDA?
We could use an attribute. But I don't think it would be possible to use
an UDA. Currently the compiler doesn't know anything about a particular
UDA, all UDA's are treated the same. It it's either a built in attribute
or an UDA. Doing something in between would be a lot harder.
It seems contain some different things/syntax. I don't know how much
Walter&Co will appreciate it.
I would say that it's very little new syntax, surprisingly. But
semantically there's a lot of new stuff. But the core things are just
the same as with extern (C), making D ABI compatible with another
language, Objective-C. I think that this is mostly is a non-breaking
change. All new keywords are prefix with two underscores, which is
reserved by the compiler. A lot of stuff only apply for classes/methods
declared as extern (Objective-C).
* extern (Objective-C) - I wouldn't really consider this new syntax
* [foo:bar:] - New syntax. Does not have to use this exact syntax but
the functionality it provides is essential.
* Constructors in interfaces - Not really a new syntax. Just allows an
existing syntax to be used in a new place.
* Foo.class - I guess this technically is new syntax. The only thing
making this new syntax is the use of keyword. I we really don't want
this we could rename it to __class or similar.
* __classext - Not implement yet, so that's up for discussion
* String literals - No new syntax. Just an implicit conversion added
* BOOL __selector(NSString) - New syntax. Kind of essential to have.
* Foo.protocolof - Not really a new syntax either. I don't think this is
as essential as the other features.
* @IBOutlet and @IBAction - Not implemented. This could possibly be
implemented as dummy UDA's.
* Blocks - Not implemented. I'm wondering if we could use the delegate
keyword for this. If a delegate is marked as extern (Objective-C) it's a
block. Or that might perhaps be confusing.
