Supposedly "every browser" (what, all of them?) already support a de 
facto extension to the JSON standard, allowing more flexible quoting. In 
an ideal world, yes the standard should change to conform to what "all 
browsers" do, since what they do is sensible. In my opinion, Python's 
handling of quotes simply is The Right Way To Do It.

But more realistically, I think a more attainable solution will be for 
json.loads() to give a better error message than "Expecting property 
name" when you use the wrong quotes.
