The value of a library is not just that it does a thing you want, but that it doesn’t do all the things you’d prefer it didn’t. It’s easy to write a cookie parser for a simple case; clearly your robot was able to hand you one for millidollars. How confident are you that you’ve exhaustively specified the exact subset of situations your code is going to encounter, so the missing functionality doesn’t matter? How confident are you that its implementation doesn’t blow up under duress? How many tokens do you want to commit to confirming that (reasoning, test, pick your poison)? |
