Hah, I have seen that one somewhere else ;)

Hey @danieldietrich,
I didn't though you'd see that.

In fact, I am just testing pre-releasing and Deno an NPM for a PR that I have going on.

I wouldn't just steal your utility without asking you first :)

About actually including IsEmpty<> I am divided.
On one and it's something that I need all the time, to make sure that I didn't forget to deconstruct any properties of an object, it is super handy.

I often do

const {foo, bar, baz, ...rest } = obj

assert<Equals<keyof typeof rest, never>>();

I don't really need a utility but it does look cryptic to my colleagues, the following would make the assert statement much more transparent:

const {foo, bar, baz, ...rest } = obj

assert<IsEmpty<typeof rest>>();

So I think it might be worth including.
I also think I should maybe rearrange the documentation and gather under a unique section all helper types that are meant to be used with assert<>()

Anyway, I'll close this for now but to be continued. :)

PS: I have opened an issue that I think if implemented properly could be game changing.
#18 I'd love to know what you think.

Best regards,
