Error if input name with number

[pvlv]

Are you submitting a bug report or a feature request?

If input name attr string with number --> <input name="323412" />, I have error "Cannot set a numeric property on an object".

I think this bug happens, because:

// final-form/src/structure/setIn.js

isNaN("4325243")  ===  false // true

isNaN("string_key")  ===  false // false

Due to the way it processes arrays of field, Final Form does not support numeric field names. You'll have to prefix them with a non-numeric character.
