bug#64290: “named-let” doc bug?

[Shynur Xie]

The following code seems fine semantically and grammatically:

    ;; -*- lexical-binding: nil; -*-
    (named-let f ((n 1))
      (dotimes (i n)
        (f 0)))

But it throws error.

Perhaps we should clarify that “‘named-let’ works as expected only
when ‘lexical-binding’ is enabled” in relevant doc?
