Which particular delta between the title and the content gave you extreme pause?

It said "jank is C++", which I assumed would be explaining that jank compiles down to C++ or something similar, i.e. there is a layer of abstraction between jank and C++, but it effectively "works like" C++.

On re-read, I recognize where it is used in the article:

"jank is C++. There is no runtime reflection, no guess work, and no hints. If the compiler can't find a member, or a function, or a particular overload, you will get a compiler error."

I assume other interop scenarios don't pull this off*, thus it is distinctive. Additionally, I'm not at all familiar with Clojure, sadly, but it also sounds like there's some special qualities there ("I think that this is an interesting way to start thinking about jank, Clojure, and static types")

Now I'll riff and just write out the first 3-5 titles that come to mind with that limited understanding:

- Implementing compile-time verifiable C++ interop in jank

- Sparks of C++ interop: jank, Clojure, & verifying interop before runtime

- jank's progress on C++ interop

- Safe C++ interop lessons from jank

* for example, I write a lot of Dart day to day and rely on Dart's "FFI" implementation to call C++, which now that I'm thinking about, only works because there's a code generator that creates "Dart headers" (my term) for the C++ libraries. I could totally footgun and call arbitrary functions that don't exist.

  • My reasoning is this:

    jank is written in C++. Its compiler and runtime are both in C++. jank can compile to C++ directly (or LLVM IR). jank can reach into C++ seamlessly, which includes reaching into its own compiler/runtime. Thus, the boundary between what is C++ and what is Clojure is gone, which leaves jank as being both Clojure and C++.

    Achieving this singularity is a milestone for jank and, I think, is worthy of the title.

    • FWIW, I saw that the title was false (after all, Jank and C++ are two different things), but I assumed it was playing on the snowclone "Are we _X_ yet?" and therefore the blog post was going to be explaining why the answer to "Is Jank C++ yet?" should be "Yes, Jank is C++ now."
