Perhaps the Standard allows this, but I consider it is an overcomplicated
code for something that can be written more simple.

If you want

(let ()
  (define x 1))

why don't you just write

(let ((x 1)))

which is more comfortable.

If you don't neet a let, then don't use it.

 I will not offer any comment on this, but my mother sais it is the best
book.

The intention when writing the book is to make a readable text easy to
understand.
I hope it is better to read the book than to dive into the standard. In
my oppinion, it is good to know the standard definition, but perhaps first
a good introduction is preferrable. If the book covers the needs or not,
ask someone who has already read the book, because it is expensive.
