Steps to reproduce the problem:
In the console -

console.log(window.open)
> function open() { [native code] }

What is the expected behavior?
It would be very useful to have the native function's parameters displayed in the log. That would save many, many MDN look-ups for the DOM API and save a lot of time. Most often, just having a hint at the parameter names is enough to avoid reading the docs.

console.log(window.open)
> function open(url, name, features) { [native code] }

What went wrong?
Nothing went wrong. This is a small feature request.

Did this work before? N/A
