...that's how chaining method calls end up working in most OO languages (take the Scala example in OP's article). And also in Javascript (I can't remember if there is something like `range` in js right now...):

    [1,2,3,4,5,6,7,8,9,10]
      .map(function (x) { return x + 2 })
      .reduce(function (a, b) { return a + b })
so the "." in OOP ends up working like "->" or "->>". Heck, you can make the dot in OOP code behave like anything, even like monadic bind (`>>=` or `do` notation in Haskell), if you do OOP-style-monads in JS: https://www.youtube.com/watch?v=b0EF0VTs9Dc

(off-topic: this is also my main problem with OOP... the "." can actually end up meaning anything practically, as program logic is concerned, it's like some kind of "infinite operator overloading" :) )

But (conceptually) the "." in most OO languages is something that is part of the object it's being applied to, while the -> is something external that one applies to the subsequent expressions. At least, this is what I perceive by looking at the code, and in my opinion, the two concepts don't map intuitively.

No (at least not in one specific OO language, namely C++).

"foo->" means exactly the same thing as "(*foo)." That is, you use "." when you have an object, and "->" when you have a pointer to an object.

I don't know of any other OO language that uses "->". If there is one, my comments here probably do not apply to it...

(Or were you talking about the "." as used in OO, compared with the "->" as used in Clojure? If so, disregard this comment...)

I'm afraid I was :)
