This is so much theoretical that I think this should be removed from the D docs. And to be put back when one DMD compiler is able to do this. Otherwise it's just false advertising :-)Is this even possible without LTO/WPO? Extending a class defined in a library you link in (and for which codegen already happened) is certainly possible…David
This is not even possible with LTO because new classes could be loaded at runtime. Could somebody please fix this.
