Uhm ... just one question: why? There are rate situations where such features 
really are needed. So while I agree that there are (some) situations where such 
(theoretical/academical) add ons might be 'nice', I much more fear languages 
which are too complicated, bloated, have too many features etc. ... and I know 
what I am talking about, I earn my living writing C++ code...;-)

Smart (the car company) once had a brilliant PR strategy saying: Reduce to the 
max! This is exactly what we need and what makes ObjC such a beautiful 
language!

Well.... I should actually agree, esp. after my statement above, *but* did you 
ever do maths in ObjC ... *Very* ugly and *very* annoying (not to speak of 
string handling in OpenStep/ObjC...).
 
Anyway, let me throw in another issue. Coming from a parallel world (SGI 
machines with only 1 CPU are bastards...grin) I'd vote for another feature:

- synchronisable blocks and methods

But then, maybe this would do harm to the simplicity of the language as well...
