I’ve written some magic templates that I assume are not easy to read by those who don’t know.

But this is seemingly unmaintainable… terrifying… and kind of neat.

After 5 minutes of staring at it: Its typesystem sudoku. Each row and each col in the grid must add up to 15 (T<>), bit each number in the grid must be different (Df<>).

Grid will only be a type alias for the value true (google “Dependent types”) only if all Type Parameters (wich are values) hold up to the Sudoku conditions).

The file would not compile with “true as Grid” when grid type-aliases to false.

Fun to understand.

EDIT: too late

I like to think I can usually look at code in languages I don’t know and still get the gist of what it does but I am drawing a complete blank. Is this even slightly legible to anyone and if yes please explain
