Speaking as one of those people who consistently fail to make this
distinction, I fail to do so because I see no distinction to make.
Exactly! And OOP does not exist. I can encapsulate data structures and
operations in Modula 2. An object is a module, and a message is a
procedure call, and that's it. After 25+ years I'm still wondering what
all that fuss about Smalltalk, C++, Objective C, Java and other so
called object-oriented languages is.
(For the irony impaired: this is irony.)
