They are symbols:

> | \(setf\ seq-elt\) is a byte-code-function in ‘seq.el’.

See those backslashes?
It is the symbol returned by (intern "(setf seq-elt)").

In Common Lisp, you can define those functions for example with

    (defun (setf my-foo) (...) ...)

and ELisp supports that to some extent as well, tho currently
not for `defun`.
