My question is why -> instead of . for method/field access. I see almost all of the examples using -> but a few use . but unless there’s a difference (like how in C++ -> is a pointer dereference access), I think -> just adds noise to the syntax needlessly . The documentation doesn’t appear to explain when to use one over the other, or perhaps . is a typo.
