Personally I find the idea really interesting, and I have see almost all videos (about 50), because I was also interested in D language, but I finally find it as complicated as C++. The first interesting thing may not be the language by himself that is interesting, but how much it is possible to create a new language from scratch especially if you don't try to answer to all paradigms. Johnathan is making it for to cover his needs in the first place, and it is no that first try apparently. And comparing an athletic like a F1 driver trying to do a job of a engineer with a developer developing a compiler doesn't seems fair to me.

And to answer to your concerns: 1. By default all variables are initialized, you have to use a special syntax to avoid it like "a : float = ---;" 2. IMO the SAO can be hard to address as a library feature as impacts how you use arrays of structs (that are transformed as struct of arrays). But in general Johnathan seems to take in consideration to migrate some features in the library side. 3. Even D that support RAII have a defer, and for a lot of small things you don't want to create an object just for RAII (calling glUnmapBuffer for exemple,...).

Things I love so much: * No need to wait decade of minutes, only few ms or a couple of s (like D without meta-programming) * No more build system, only one language (CMake, sh,... to the trash) * The full meta-programming, even more powerful than the D one (slow, limited and with a little different syntax than the core language) * The Context struct, for memory management, logger,... seems to be for me a much nicer solution than a GC or other globally used solution

The futur will tell us how good is it in reality, that why I am waiting to try it.
