for example, the regex [a-zA-Z] only cares about two kinds of characters: letters and everything else. so instead of individually taking derivatives for 52 alphabet characters a..z, A..Z, we can conclude from the start that there are only two kinds of characters we care about: letters ([a-zA-Z]) and non-letters ([^a-zA-Z]).

In traditional engineering, teams put 90 percent of their time into features and 10 percent into everything else. Work that isn't a feature feels like a distraction—something you do when you have spare time, which you never do. But that \"everything else\" is what makes future features easier: things like creating review agents, documenting patterns, and building test generators. When you treat that work as overhead instead of an investment, the codebase accumulates debt.

Instead of all that boilerplate to make a new object, we basically just write a block of code that will be used by the function we’re calling. What’s interesting here is that we’re not in complete control when that block of code is running. It might appear like it, but we can’t do anything except give a value back to the function.
