Objective-D released!

[DanielG]

Hijacking this thread a bit to ask a related question:

What's the overall feasibility of using pure D to rewrite a 
not-too-large amount of Cocoa/AppKit code?

Is it just a matter of translating the headers via 'dstep' or 
whatever? Does that work today, for something as complex as 
AppKit? (Also I'd need Quartz2D and CoreText, but I'm assuming 
those would be trivial since they have C APIs)
