In its defense, this is the system used by Python, and I don't think I've 
heard it to cause any confusion once it has been explained.

Jeni has already pointed out the problems with [] and {}.  I know you weren't 
convinced on {}'s interfering with AVTs, but I do think we should avoid using 
them, especially in such a central manner.

I do think we should come up with a syntactic solution to this, rather than a 
list constructor in the core.
