Bosque Programming Language
At this point any new systems language aiming at productivity has to prove itself not just superior to C++, but superior to Rust, without being significantly worse in any aspect. It’s already suspicious by virtue of having a hand-wavy "Int" type (what size/signedness is that?) and it appears to be object-oriented (so we have to rely on compiler optimisations to remove dynamic dispatch) and garbage-collected (so by default any non-trivial type is heap-allocated). These are just ways in which it is worse than Rust as far as performance goes, since "ergonomics"/"productivity" is so subjective. It seems to improve on C++ only by taking the most common C++ patterns and building them into the language so the language doesn’t have to be so immensely complicated, while also improving the syntax. That’s simply not enough for a modern language to be competitive.
