Local storage only stores strings

[GoogleCodeExporter]

What steps will reproduce the problem?
local_storage["foo"] = [1,2,3]
print(local_storage["foo"][2])

What is the expected output? What do you see instead?
Should be "3", I get ",". Brython should serialize and deserialize 
local_storage values.

Thanks for the report and the proposed implementation by Bill
It's fine for me, but I am going to post a message on the forum to see if all 
agree on local_storage using JSON transparently, or if we should let it store 
strings and ask the programmer to explicitely "stringify" and "parse" using JSON
Anyway, with this issue in mind, I recently added a built-in module json.js 
that implements these functions :

import json
x = json.stringify([1,2])
print(json.parse(x))

You can test it in the console on the Brython site

Bill, Pierre thanks for the answers, Bill solution is nice but only works for 
lists (it doesn't work for strings). The built-in json.js seems nice but it 
isn't capable of deserializing dicts, for example. I think local_storage should 
be transparent so it could be more reliable.
