Short answer, no. I'm sure it's been proposed before. Attributes ≠
keys. When you see something.somethingelse anywhere else in Python,
"somethingelse" is an attribute reference. When you see
something[somethingelse], "somethingelse" is an index value or
key. Why destroy that symmetry in dictionaries?
JavaScript objects have that feature. I find it mildly confusing
because whenever I see it I have to pause to consider whether the name
I am looking at is an attribute or a key. This little JS code I just
typed at my console prompt was also mildly surprising:
> var x = {};
undefined
> x.valueOf(47)
Object {}
> x["valueOf"] = 12
12
> x.valueOf
12
> x.valueOf(47)
TypeError: number is not a function
Still, in my own JS code I tend to lapse into that usage, probably
because so much other code out in the wild uses dot notation for key
references. (Doesn't make it right, just makes me lazy.)
