you do realise this is essentially a joke right?
I'm sure every language has examples of code where it was written to be crazy on purpose, This is one of those.
Like when you write a raytracer in CMake, or Meson build, or C++ templates. Etc etc. Or when you compile your program to only mov instructions, because mov instructions are turing complete (should this be a reason we shouldn't use x86?). I'm sure there are plenty more examples.
Nobody is suggesting you actually use this stuff. Therefore it seems a bit silly to point at it and say 'don't use this language because people do silly things for fun in it!!!!11!!1'
