Use it like this:

    import {update} from 'update';
    let obj = { a: 3, b: 'horse', c: { d: [1,2,3] }};
    let obj2 = update(obj, { a: 0, c: { d: _ => [..._, 4] } });

// This is what imperative style looks like when the parser is
// implemented with exceptions for control flow
function imperative_style_with_exceptions(p: Parser) {
    p.consume('look at'); // could throw NoMatch

    let who = p.split([ // could throw Split or NoMatch
        () => p.consume('me', 'me'),
        () => p.consume('mewtwo', 'mewtwo'),
        () => p.consume('steven', 'steven'),
        () => p.consume('martha', 'martha')
