Issue Type

Description

I'd love to have Symbol.iterator implemented on the Result data structure. This would enable destructuring assignment, spreads, etc, when handling values returned from contracts. Additionally, iteration should only be performed over numerically indexed keys.

Steps to reproduce

Using the decodeParams function with any valid parameters, the following code will currently throw:

const [a, b, c] = decodeParams(...);

Only the following works currently:

const result = decodeParams(...);
const a = result[0]
const b = result[1]
const c = result[2]

Versions

Node/NPM: 8.6.0/yarn@1.1.0
