This post series explores an Action in detail with emphasis on the Instance objects, especially the dynamic (temporary) ones. Posts are broken up mainly for size considerations.
One language question designers need to address is whether objects are passed by value or by reference when invoking callable objects. It’s common in object-oriented languages to pass by reference to avoid having to build copies of passed objects.
BOOL uses pass by reference, which begs two questions: Do we provide a means to pass by value when desired? And if so, which side — caller or callee — can do the magic?
There was meant to be a third article in the Native Objects series that would discuss the Actions (“methods”) supported by the native Models (“classes”). But I’ve only begun to define those things. For now, suffice to say that typical data types (integers, floats, strings, etc.) have the methods you’d expect. Assignment for all, basic math for the numeric types, stringy stuff for the string; you get the idea.
I’ve reached another major milestone, but I’m also about to begin another design phase as I figure out exactly how to implement the native Models. And I may be taking a break from this blog to give BOOL a rest and to deal more with other matters.
