I think that the most interest in making this is not because the c compiler is insufficient or the glib is a bad runtime.
Vala depends heavily on glib, not only because of the language design, but also in stuff like regex, class inheritance, etc. Maybe we can focus in letting vapis interface with c++, objc or rust. There are many c++ libraries out there and calling c++ from c is not possible, so it needs the code to compile against g++. But then we need to be able to construct c++ syntaxes for calling methods and instantiating classes. The same applies to objc. In ios and osx, the system provides a full objc api which can be used from swift. But again, what i think that we need is a thin layer to allow sub-vala language to call c++ or objc code. Then we can use this wrapper code to interact with the vala code we already have. That would be one approach, which doesnt solves all situations but it doesnt makes things much harder for the compiler. > On 10 Nov 2014, at 00:19, Luca Bruno <lethalma...@gmail.com> wrote: > > There's no need for a plan to make the compiler more generic.
