How about ['a':'1', 'b':'2', 'c':'3']? (for ordered dict literal)
I really find this sensible. We have then: * [a, b, c] & [k1:v1, k2:v2, k3:v3] for ordered containers * {a, b, c} & {k1:v1, k2:v2, k3:v3} for unordered ones
+1.0 for me
Update: confusion of 1-item ordered dict with slice? Or just the same as confusion of 1-item list with index? (Note: have always found that [] and [:] for index and slice was somewhat wrong).
Can you confuse a 1-item list with an index? No, because the syntax/grammar disambiguates them. Is that also the case with a 1-item ordered dict vs a slice? In Python 2.6, [0 : 1] (== slice(0, 1)) raises SyntaxError. Does that also occur in Python 3.x?
