I like this a lot. The effort to avoid new keywords, though laudable in 
many ways, comes at the cost of increased use of punctuation.

I generally find punctuation harder to read than keywords. Also, it is 
usually incomprehensible to someone unfamiliar with the language. The 
relative lack of punctuation in python as compared, say, to C is one if 
its great strengths, to my mind. It is one reason Python reads so much 
like pseudocode (or did before some of the recent changes such as list 
comprehensions -- very useful but a classic example of the problem of 
overloading punctuation).

I'd be very sad to see [] used for yet some other purpose.
