Yeah, I didn't intend to attribute malevolence; you wondered how I read
sarcasm (which, even if it might not be the best technique for
communication, isn't the same as ill-intent) in your message, so I
explained.

Although I do believe you meant it that way, I still struggle to read
this as a compliment, even with the added explanation.

The idea is recommend using eql for comparing integers first, and move
the description of eq and fixnum/bignum distinction to the next
paragraph, right?

And also to document when the reader returns fixnums or bignums.  Though
I guess that might instead be solved by making the rule you cited
stronger to something like:

    Emacs always represents integers in fixnum range as a fixnum, not a
    bignum.

(Assuming that's true, which I believe it is)
