Well that also has to do with whatever the object is
foo = {'string': value}
vs
bar = [1,2,3,4,5]
if you had in Python:
foo = {'string': None, 2: 'two'}
it should encode to json where the key is a string:
'{"2": "two", "string": null}'
With that being stated, I have no idea what happens in SqlAlchemy or the
various engines if you try to set `bar[2] = "two"'` when `bar` is a
hash/dict/object. something might raise an error, or `2` might be retyped
into the string `"2"`, or a database might possibly support an int as an
object key (I have no idea if any of these happen, just rambling on
potential compatibility points).
