Many thanks.

I was aware that everything boils down to lambda functions in lisp but
it hadn't occured to me that they are self quoting in all contexts,
although now I think about it I realise they _have_ to be
self-quoting, given that they are one of the fundamental building
blocks...

(info "(elisp)Anonymous Functions"):

  In Lisp, a function is a list that starts with `lambda', a byte-code
  function compiled from such a list, or alternatively a primitive
  subr-object; names are "extra."
