README error? claims that capture() retrieves return value instead of arguments

[cspotcode]

In the README

const foo = { bar: () => 42 };
const spiedFoo = spy(foo);

foo.bar();

console.log(capture(spiedFoo.bar).last()); // [42] 

It seems to imply that capture() can be used to retrieve the return value rather than the arguments, which I'm pretty sure is not correct.
