JIT is even worse, as if you have ever built a compiler one already knows about why backpatching is needed during the generator stages. I cringe every time someone brings up embedded python, and lose hope for future coders.
I agree it is subtle, so takes some people a few hours to understand, and for others never. If you work in Application user-space, than it usually won't matter. Note I like Julia, but it is also not a good fit for SDR or low-latency DSP.
People seem upset for some reason, but one may want to check out Analog Devices training documentation as a student. =3
