I think it's fair to say that the Racket style guide is not as rigid as
some other style guides for some other languages: as it says itself in the
introduction, it "isn’t complete and it isn’t perfect" and is more a set of
"guidelines and best practices" than binding universal rules. I think it is

Yes, I hadn't really thought through the semantics of define (i.e. whether
it had let or letrec semantics). So, in my case, since I want let
semantics, I will use let. I'm happy to follow the Racket style guide when
I get to the point of contributing code that is covered by it, but I think

To be fair:
As a new user, it's possible to have the intuition that `define` is
just a way to avoid indentation -- that it "writes a `let` for you,
from the point of the define to 'the end of the enclosing scope'".
And it's possible for that intuition to seem correct for a very long
time --
