It is precisely this abuse of notation which makes, for instance, statistics textbooks impossible to read (without already knowing the material).
Hmmm, I don't find statistics books difficult to read.
I'm interested in a technique called Correspondence Analysis. I recently bought a book about it. The author comes from the UK, but was trained in CA at its home in France. And the book is very nearly unreadable, thanks in part to some of the strangest overloading I've seen. I don't have it handy, but things like f(i) and f(j) having different types is just the start. (No, this is not dependent typing. Which type the result is depends on the *name* of the argument, not its value!)
