[...await x] is already valid syntax. [await ...x] was mentioned in the issue you linked and is not valid syntax, so using that would probably be ideal.

It throws errors in combination with generators. Should it be already supported in node v13?

Hello Misiur,
thank you for your idea!

Notice that the iterator-helpers proposal already covers this use case:

const values = await gen().toArray();
const somevalues = await gen().take(2).toArray();

No need to strain spread syntax.

Awesome, rxjs integration with lazy evaluation sounds awesome, but still, spread syntax support would be great.

I like this idea a lot (mod @devsnek's nit, of course). Makes some things trivial like reading a stream into a buffer (with Buffer.from([await ...x])) and getting the last N items in a stream (with [await ...takeLast(n, x)]).

Reflected the await position change.
