You forgot that beauty - “undefined behavior”!
Memory-safety can guarantee only so much safety! C++ can still blow up in your face, even with all the alleged memory-safety built into C++, thanks to all the UB traps in C and C++.
Rust is the closest language that has no such “gotchas”.
C on Morello (or any other capability machine).

C++ with -Wall -Werror, and no pointer diddling.
Its definitely best to try and avoid raw pointers, but even if you try really hard I found it’s not really possible to get a Rust-like experience with no UB.
Even something as simple as
std::optional
- you can easily forget to check it has a value and then boom, UB.The C++ committee still have the attitude that programmers are capable of avoiding UB if they simply document it, and therefore they can omit all sanity checks.
std::optional
could easily have thrown an exception rather than UB but they think programmers are perfect and will never make that mistake. There are similar wild decisions with more recent features like coroutines.They somehow haven’t even learnt the very old lesson “safe by default”.
If I wanted memory unsafety I think I would consider Zig instead of C++ at this point.
C# is good too. If you havent heard of lobster you should look into it.
C# isn’t exactly compiled, at least not into machine language. It is transpiled into byte code that is run on a virtual machine that on turn is an interpreter/JIT-compiler.
Depending on why someone is asking for a compiled language that may or may not be a problem, because to the one writing the code it looks like a compiled language, but to the one running it it looks like an interpreted one.
It is compiled into bytecode. A transpiler translates to another programming language with the same level of abstraction. A compiler translates into a level that is nearer to or machine code.
Rust
With no context, this could be an honest attempt to learn about different tools, a thinly veiled set-up to promote a specific language, or an attempt to stir up drama. I can’t tell which.
It’s curious how such specific conditions are embedded into the question with no explanation of why, yet “memory safe” is included among them without specifying what kind of memory safety.
Yeah, arguably the only answer to this question is Rust.
Java/C#/etc. are not fully compiled (you do have a compilation step, but then also an interpretation step). And while Java/C#/etc. are memory-safe in a single-threaded context, they’re not in a multi-threaded context.
The question mine as well be “what is your favorite compiled language?”. There is a lot of overlap between the possible answers.
As others have said, Haskell and Rust are pretty great. A language that hasn’t been mentioned that I REALLY want to catch on, though, is Unison.
Scala 3 native. If the compiler was faster I’d be even happier. Curious to try Ada

OCaml.
Sad I had to scroll to the end to see this.
Ocaml is brilliant and has the nicest type features. It’s almost like Haskell but more approachable imo.
I’ve recently been trying to learn OCaml and find it really nice. The major pain points are
- C-style separate compilation with manually created headers
- Small standard library
- No generic print function
- Hard to use external libraries
Rust and Haskell (I think Haskell counts)
