I really think D, like Go has a better chance of attracting programming languages from higher, not lower level languages. C++ can't event get the C greybeards to switch over while being a strict superset. On the other hand, Go is being embraced as a python replacement in the backend world

pedant here: C++ is far from a strict superset of C, with many syntactic changes over the years.

  Yes, at this point they're disjoint https://en.wikipedia.org/wiki/Compatibility_of_C_and_C%2B%2B https://en.wikipedia.org/wiki/Compatibility_of_C_and_C%2B%2B

  C++ is actually missing some of the nicer stuff from the last few ANSI-C standards. Struct initializers especially.

    That is what constructors are for. In any case, they might make it into C++20. http://en.cppreference.com/w/cpp/language/aggregate_initialization http://en.cppreference.com/w/cpp/language/aggregate_initiali...

Rust is hard. But languages live and die by mindshare. Can D run on a 20k microcontroller?
- pjmlp 9y ago
  Maybe, if stripping the runtime and making use of the betterC compiler mode. In any case, with only 20 KB available, the only sane option is Assembly, as every byte counts. Any kind of high level programming just means using a crippled language, trying to match Assembly, while wasting more space.
  - MrBuddyCasino 9y ago
    Well, Rust can. I‘ve spent the last week to see if its true. But I wished it was easier.
    - pjmlp 9y ago
      With 20KB available it hardly is Rust anymore. Just like C and Pascal compilers, the result with hacks to make the generated code fit and beat manually written Assembly is not worth it. It would also be possible to do it with D, using betterC mode and no runtime, assuming a backed for then target architecture would be available.

        To clarify, I was talking about RAM, not flash. Binary size is still a problem, thats true. And yes of course you need to go the no-std route, but it works.

    What about Forth ?
    - pjmlp 9y ago
      Yeah, sweet memories of FORTH, but 20 KB is not something one wants to "waste" bytes and you would need a few of them for the dictionary and basic words.

  How often do you use the restrict keyword, seriously?
