AW: Convenient array & hash iterators & accessors

I just wanted to throw „Rust“ into the discussion.

Rust seems to have a very expressive type model, which allows to handle most of the memory management automatically and compile-time-safe.

It also allows to go very “low level” / “lean” (they even wrote bootloaders and POC Kernels with it).

It is compiled to native code, and has rather good C interfacing capabilities.

On the other hand, I tend to oppose C++. While it feels “natural” to “upgrade” from C to C++, the mere complexity of that language makes it very difficult, at least if a project does not restrict itself to a very well thought, strictly defined subset.

I understand the point. I note that "explicit" is not a binary quality: there are degrees of it.

I suppose I want to be writing in a higher level language. Maybe I should just go ahead and really do so.

Exactly. There's been talk about doing so for much too long without action (other than attempts - including my own) to find a way to "upgrade" C to something less verbose and more expressive.

I've been long thinking that there are specific areas which are more-or-less stand-alone, might be a good place to start this strategy. One place like that might qualify is the piece of code that deduces the eligeable revisions in merge tracking. That's the code I'm thinking you're now working in?

What kind of language were you thinking about? One of the languages that came to mind is 'lua' which seems to have a pretty strong focus on being integratable with C code. For lua there are also tools to embed the compiled bytecode in a C library so the entire higherlevel language can be fully encapsulated inside our libraries.
