Splitting by one value or another seems to be a pretty common use case if
Stack Overflow questions and personal experience are an indication. For

Currently, the solution is to pass a regular expression to

However, it would be nice to be able to
Keep in mind that if an object is non-extensible, its [[Prototype]] cannot
be changed.

And objects that are implemented using a Proxy don't use their [[Prototype]]
slot (a Proxy they doesn't have one) or necessarily even their target's

Of course, this is another way to do it that does not require knowing

yeah, if you use an alias L the footgun image comes upside down too
```
L.__proto__ = null;
// later on, in ES6
L.__proto__ = () pew, pew;

maybe it's better to explain those users that knowing RegExp might bring
benefits for their purpose (coding) ?

Yes, that's true, not sure how that works for multi character delimiters.

This proposal does not break anything, the only thing that will/might work
differently is people passing an array to .split right now and
It does break in many ways as also Brendan said.
`''.split(what, ever)`
would break
plus
`some1,2thing.split([1,2])`
you have no idea what you could find in legacy code ... so whatever a 12+
years old legacy does shold keep doing like that and if you really want to
put your array in there
The relevant invariant for [[SetPrototypeOf]] is that if the target is
non-extensible, and the operation returns true (i.e. appears to succeed),
then [[GetPrototypeOf]] must return the same result as the value passed
into [[SetPrototypeOf]].
This is what I got from the current ES6 draft:
also, to reply your question Are you against changes like `.contains` or
`.startsWith` too?
Absolutely not, and these are new methods indeed. Perfectly in line with
what you wrote:
Why have `str.contains` if you can just do `~str.indexOf`. Why have
`.startsWith`, or `.indexOf` on arrays?

What about the version with the overload accepting an Array instead? It
seems more backwards compatible than the varargs version.
I meant the version accepting an array `.split([a,b,c])` rather than
