No functions support

[20NickName20]

If table contains function, this happens: " json.lua:130: unexpected type 'function' "

Trying to encode values which are unrepresentable in JSON will never result in type conversion or other magic: sparse arrays, tables with mixed key types or invalid numbers (NaN, -inf, inf) will raise an error
