Re: [Vala] Can adding new virtual method break ABI?

If you need to do these things manually, then what's the point in using vala? It's the job of compilers. People who like to do the job of compilers manually should use GObject/C instead. Manually filling a virtual function table and calculate offset of pointers are really of fun. lol Creating some
