Hi chris,

I'm not sure I understood what you meant exactly but here are some  
points to explain
what drived us:

	- the code in the image should be homogenous so having := consistently
	would be better than having one methods with _ and one with :=

	- we tried to ease the transition between Squeak and the other  
Smalltalks which
	(as far as I know but I can be wrong use :=).

	- people can use the characters they want for their code
	
	- I would loved to get a consistently formatting and I believe in  
your increase in productivity ;)
	I hope that the pretty printer a guy here is doing will be cool  
enough so that everybody can use it
