      I don't want to attack the OP specifically (please don't go after them), and I won't argue directly with the C++ part, but C is a terrible C. Later on the OP bemoans fragmentation, but Go is a way better C than C ever was, and Rust is a way better C++.https://twitter.com/landley/status/983060536714780672 …

      C is very good at what it does. C++ is terrible at what C does. You will never convince a C++ developer of this.

      I really don’t think Go brings anything to the table, FWIW.

      Things I actually want from a “better C”: - support for manipulating alignment in the language. - idiomatic bitcast. - vectors in the language. - machine model with twos-comp, CHAR_BIT=8, IEEE 754, flat memory. - restrict-by-default. ...

      I think adding a conservative, sensible compilation model (flat modules, acyclic deps, visibility control), a typesafe fat void* you can punch in and out of, fat bounded pointers / arrays, and ARC (with weak pointers) would be a good stopping point too.

      (But again, I think it's worth noting that a lot of the nice things one might want from such a Demi-Go is actually just ObjC. It reads funny, but it's not a bad language!)

      Pervasive atomic reference counting and hash table based method dispatch is such a bummer though.

      objc_msgSend is pretty fast. Without the late-binding semantics baked into the language banning any sort of static devirtualization or specialization it'd probably be much less of a big deal

      Throw an inline cache at it and call it a day. You wanted late binding, you got it. There’s always function pointers, or just functions.

      It’s not the method call overhead that’s the problem—it’s the fact that it’s hard to do the really valuable interprocedural optimizations when you can’t devirtualize.

          Of course, it’s an opt barrier for a static compiler. I wish we had some middle ground where most things are static but some opts (dynamic const prop would be huge) are lifted to runtime—single-shot JIT points. Heck, devirt alone, w/o any further work, can make a big difference.

          ObjC makes it /really hard/ to allow devirt /ever/ because of method_exchangeImplementations and similar.
