Not that my opinion matters a whole lot, but I prefer the redundant  
syntax.  This new syntax solves a problem, and introduces a problem  
which (in my opinion) is worse.  In python, I am used to syntax:

for var in stuff:

where my eye finds "var" and then "stuff", so I first find out the  
relevant variable, and then the values it will take.

in old pyrex syntax,

for var in begin<= var < end:

my eye finds "var" and then "begin" and "end", so I first find out  
the relevant variable, and then the values it will take.

In the new syntax,

for begin <= var < end:

my eye finds some values of var, then the relevant variable, then the  
end.  It changes the logic of the for-loop organization in my head,  
and as I read.  It makes it less like Python, and thus more jarring  
to go between the two.

Personally, I never minded the redundancy (how much extra typing is  
it really?)

I find breaking readability, and a parallel with existing python  
syntax to be far far worse.  I hope you keep the two syntaxes, and  
see what the response is when developers actually use it for a  
while.  My gut feeling is that the new syntax will not be favored,  
but I could very well be wrong.
