Of course, D can also take ages to compile one line of code. It all depends on that that line is doing... ctfe and templates are slow. C or Java style code compiling in D is very fast.
I was going to say this too, ie how much of that Jai code is run at compile-time, how much is uninstantiated templates that is just skipped over like D does, and how much is templates instantiated many times? Lines of code is not a good enough measure with those programming constructs.
I was just building the stdlib tests with LDC yesterday and they took so much memory on a new Linux/x64 VPS with 2GB of RAM that I had spun up that I couldn't even ssh in anymore. I eventually had to restart the VPS and add a swapfile, which I usually have but simply hadn't bothered with yet for this new Ubuntu 18.04 VPS. The stdlib tests instantiate a ton of templates.
