Description of the problem

In document, described as below.

One known limitation of using the await keyword in the REPL is that it will invalidate the lexical scoping of the const and let keywords.

For example:

> const m = await Promise.resolve(123)
undefined
> m
123
> const m = await Promise.resolve(234)
undefined
> m
234

But actual result is different like below.
(1) const

Welcome to Node.js v20.0.0-pre.
Type ".help" for more information.
> const m = await Promise.resolve(123)
undefined
> m
123
> const m = await Promise.resolve(234)
Uncaught SyntaxError: Identifier 'm' has already been declared
>

(2) let

Welcome to Node.js v20.0.0-pre.
Type ".help" for more information.
> let m = await Promise.resolve(123)
undefined
> m
123
> let m = await Promise.resolve(234)
Uncaught SyntaxError: Identifier 'm' has already been declared
>

I guess limitation is fixed. So how about removing these lines(One known blabla, including example) from document?
