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
- TL;DR: Grid simplifies to true, if and only if it is a 3x3 magic square.
  
  full explanation
  
  Fifteen is an array of length 15
  
  T checks if an array of length A+B+C is equivalent to an array of length 15, thus checking if A+B+C is equal to 15
  
  And is simplifies to X if A is true, else it simplifies to false
  
  Df checks if A and B are Diffrent , simplifying to X if they are
  
  Grid first checks if every row, column and diagonal is equal to 15, then checks if every item is unique.
- Yea, i was really trying to understand… and then I was like yeah fuck this and regex too.
  
  Gotta learn regex... C++ not so much 😹
  
  Fear not, template abuse is not a necessary practice
  
  Edit: wait what is this I thought it was c++ at first. Java? C#? Has an extends keyword
  
  This is a Typescript type-level computation (which is Turing-complete AFAIK). However this kind of trickery is usually done for fun and to explore how much could be achieved just on the compile step.
  
  Lol thanks that saves me a lot of googling 😹 that makes a lot of sense
