/**
 * Currying Functions with Named Parameters.
 * @gunar, @drboolean, @dtipson 2016
 * 
 * Why does it return a thunk, though?
 *   Because in JS named arguments are opaque. There is no way of getting a function's named arguments list.
 *   e.g.
 *     const foo = function ({ a, b }) { }
 *     console.log(foo.arguments) // Throws. Ideally would return ['a', 'b'].
