What, you mean in the code? Yes, you make them either implicitly with
argument bindings, or with some kind of let statement. Is that what
you meant?

By object above, I was referring to "object of user-defined implementation type",
let's call it a struct, even though it's really more like an instance of a class...
struct is smaller. Things like integers have classes, too, just you can't
/make/ these classes via the user-class-defining-method, since they're fundamental,
and allowing flexibility into the primitive type implementations hierachy would
restrict implementation somewhat.

You're welcome to make objects that obey primitive type *interfaces*, though,
so I don't think you lose out here?

There really should be a better term for "instance of class" than "object", which
tends to cover things like tables, computers, and people as well.
