Quote-unquote "macros"
You’ve probably seen this Python 101 thing before: @memoized def fib(n): if n <= 1: return n return fib(n - 1) + fib(n - 2) Leaving aside the absurdity of computing Fibonacci numbers recursively, it’s a common first introduction to Python decorators and higher-order functions. fib is just a function, and memoized…

Like the blip of an intro on the front page says, my degree was originally in music. My running joke as a web dev is that neither has meaningfully required me to count past 32.
