Can't use ES6 Symbol as mutation types.

TypeError: Cannot convert a Symbol value to a string.

As far as I can say, Symbols are not a good fit for mutation types, because Symbols are not serializable, i.e. symbol !== JSON.parse(JSON.stringify(symbol)).
See: reduxjs/redux#4

Yeah, this is not supported because Symbols cannot be serialized.

@yyx990803 How about the global symbol registry? Symbol.keyFor() can be used for serialization.

@crimx AFAIK that requires the symbols to be created with Symbol.for(). Won't work for all Symbols :/
