> Rust cares about first-class FFI support; in particular, copying strings at FFI boundaries is right out. That is why Rust needs C strings to be a separate type. How does Rust handle strings encoded as UTF-16 or UTF-32? Does it need imm

I'd even say it's generally faster because you can use integer as template arguments for enforced constant folding. Typically in video work: make a code path specialized when block width is 8, 16, 32 etc. Something that a C compil

Maybe what the Objective-C runtime does isn't really needed? It doesn't make much sense to have every method patchable, it doesn't make much sense to be able to build classes at runtime, and it doesn't make much sense to

Why this dismissive comment? auto is definately overused in ways that are unreadable, exactly like the blog author says. Marking the type explicitely may be less generic in a way, but it helps readability so much by providing redundancy.

I've found NaN initialization for floats to be a useful default (like undefined in Javascript) since it propagates. Integer have no NaNs, so they are initialized with 0s since no other value really fits. I don't know for chars but

I once implemented a CBOR parser and found that a strange oddity.

We are seing lots of .unwrap() because Rust has no monadic notation. That replaces recoverable errors with crash.

Agreed. If you are using C++ but no exceptions, no RAII, and no std::unique_ptr, you are avoiding the best part of C++.

D offers a number of improvements in all directions: http://p0nce.github.io/d-idioms/#How-does-D-improve-on-C++17 ? The fact that is has better syntax is almost anecdotal. Same story for Rust.

Good news then. There is no shortage of speedup when we stop considering all memory being equal.

I see what you mean. You can create such new types with std.typecons.Typedef https://dlang.org/phobos/std_typecons.html#.Typedef Though it's less pretty.

Wild guess: perhaps their OpenCL to FPGA compiler. OpenCL is many times easier to program than VHDL.

GPUs are often considered "hard to program", let's see how this goes for FPGAs.

Like others said, this can be done as a library type in D: http://p0nce.github.io/d-idioms/#Recursive-Sum-Type-with-mat... edit: not that it proves anything, just that "it can eventually be done".

It's amazing you have to justify this view point. There are books precisely documenting the correlation between quality, speed of execution and lower costs. http://ptgmedia.pearsoncmg.com/images/9780132582209/

1.5 has an exact representation in floating-point, so adding 1.5 + 1.5 is always going to give you 3.0 in floating-point, also exactly represented. Then whatever the type of integer rounding you do, you will get a solid 3.

This is the reason why D and Rust keep pointers and length packed together in array slices.

Indeed. C++ is incredibly fragmented, I guess that could cause its demise before safety becomes an actual concern for language choices.

C++ is safe enough, provided you use the tools like Intel Inspector, valgrind, and static analyzers. With C++11 memory corruptions became a somewhat rare occurence.
