It's also probably the case that readability is not a primary concern when implementing things like "min" that will most likely be in the standard library of a programming language. From my limited experience looking at such source code, there tend to be a surprisingly large about of code for fixing edge cases, esoteric performance problems, etc. It may be instructive to look at how readable a very naive implementation of a basic function like "min" is, but it probably doesn't actually matter that much in practice, because you'll be using what the standard library offers (and its implementation is probably much less straightforward than you might think).
