I could present some code using objects.fs, and let you rewrite it for
BerndOOF, and if you misguess what's a method and what's an instance
variable, I could claim the same (but I wouldn't, because it's a
falacy).

I did not claim that it is, and I don't care what the VM does, if
there is one.  The language definition says that when I call
foo.bla(...), foo is the current object during the execution of bla.

The current object is one way to reduce stack depth, yes.  But not all
ways to reduce stack depth are a good idea.  In particular, passing
data in global (or user) variables to colon definitions is a bad idea.
That's why we wrap such things in context wrappers like BASE-EXECUTE,
where the base is passed on the parameter stack.

Similarly, passing the current object to a selector through some extra
state is not so great, although having >O and O> is certainly an
improvement over having to manage all of saving and restoration
yourself (as for BASE).  It's better to pass the object to the
selector and method on the data stack.

Yes.

Actually, what one could do in current standard Forth is to define two
names when seeing a selector definition, one name for your calling
convention and one for mine. But given that you won't be using
objects2 anyway, and nobody else wants your calling convention,
putting that into objects2 would just be needless complication.

I guess that taking the xt of methods (i.e., class-bount methods, not
selectors) is rare anyway.

That depends on the design of the higher-order word and the methods.
E.g., if I write a MAP-WORDLIST ( ... xt -- ... ), xt will have a
stack effect like ( ... nt -- ... ), whereas for you it would have a
stack effect ( ... O: nt -- ... O: nt ) (and your "nt" would be called
"xt2" or so).

There may be words that call CATCH internally and throw onwards (e.g.,
BASE-EXECUTE) and are defined before the OO package is loaded, so for
option 2 and 3 all of these words have to be redefined in that way.

For SIZE@ or SIZE!, how do I know that what's coming out/going in is
an n, not a d or r or an object or something else?  For SIZE, what
convention tells me anything about what it produces?

But if you want to use ":" in the names of selectors when using
objects.fs or objects2, go ahead.  I think that Doug Hoffman and Alex
MacDonald are doing it because it was necessary in Neon and some of
the followups, not because it's so hard to remember to pass all the
parameters on the stack.
