HLL/INT: What is an object, anyway?

I'd like to give more comments (indeed, have two pages _almost_ finished,
but not quite), but don't have time. I prefer to write really cooked
stuff, the noise level is high enough anyway. Just this much (raw):
- I really loved reading about MIT's `exo'kernel. That's exactly what
I want: `somewhat' standardized device drivers for the time and space
ressources. (Oops, I just mistyped `satandardized'. Does this tell
us anything about the word `standardized'? ;-) That's the equivalent
of Emacs in the field of OSs.
- What is Tunes? A protocol? A set of standard (alternative) libraries?
What is the difference b/w an exokernel and Tunes?
- Farč's object definition:
> So my definition for an object would be:
> "anything whose semantics can be finitely coded into a Turing Machine".
Oh, sh**. Do we really need that? I hope we don't.
- I'll do a 'diff Pascal Lisp'.
I'll do a 'diff C++ Self'.
I'll do a 'diff Self Lisp'.
By this I'm trying to set up a crude scheme to describe and classify
languages. Hmm - this MUST have been done before, just where is it?
Lisp stands for `functional/interpreted' as well as Scheme.
Pascal stands for `imperative/compiled' as well as C/Algol/Fortran/Modula.
C++ stands for `class-based/typed'.
Self stands for `prototypes/untyped'.
Yes, I know that those pairs are not fixed. Java for example is
class-based, typed, and imperative but (somewhat) interpreted.
Java/HotJava is a good thing - only not good enough. Maybe the java
bytecode is OK as a LLL?
Glossary entries for the languages with links to their description
in the Review project will be the right thing - gimme one week.
Could anybody write a 'diff Lisp SML' ?
Could anybody write a 'diff Lisp Haskell' ?
Could anybody write a 'diff Self BETA' ?
Ciao, Rainer
