source/appdelegate.d(47): Error: function
appkit.tableview.NSTableView.setDoubleAction (objc_selector*
aSelector) is not callable using argument types (extern
(Objective-C) void __selector(ObjcObject))

Line 46 & 47:

auto doubleAction = &AppDelegate.doubleClickAction ;
demoTableView.setDoubleAction(doubleAction) ;

Line 80:

void doubleClickAction(ObjcObject sender) {

actually, when line 46 & 47 are like above, it doesn't matter if
I change ObjcObject to NSObject, but I guess my problem here is
how Map the function in tableview.d:

void setDoubleAction(objc.runtime.SEL aSelector)
[setDoubleAction:] ;

I know Dip 43 almost by heart now, but I haven't yet discovered
the tests you wrote. Nice, this will be extremely helpful.

Best!
