Different indistinguishable dicts

[CoffeeImpliesCode]

Hi, I noticed (after some troubleshooting) that dicts created by (dict ...) and by (python-eval "...") look exactly the same but behave differently:

(define a (python-eval "{'a' : 1}"))
a                                                           => {'a' : 1}
(define b (dict '(b : 2)))
b                                                           => {'b' : 2}
(get-item a 'a)                                             => 1
(get-item b 'b)                                             => error
(get-item a "a")                                            => 1
(get-item b "b")                                            => 1

While I know that that behaviour is to be expected, couldn't its representation be different to emphasize the incompatibility? e.g. b => {"b" : 2} or change the symbol-based one a => {'a : 2}

If you could make a pull request, that would be great.

Fixed in Calysto Scheme 1.4.8. All dictionaries use strings as keys, but now will automatically convert symbols to strings if needed. Thanks for reporting!
