> I don't care how wizard you are at shovelling, you aren't going to out-perform the back hoe. 80% of the time you want to know what's 10cm below the surface, and a shovel is every bit as good (better, since you don't have to go and start the backhoe). If you're in the position of working on simple problems, it's very hard to justify the work of learning these tools. Back when I worked on a multithreaded database engine, I would have killed to have `rr`, but when I'm trying to get simple procedural code right it really does seem like a lot of hassle.
