Assuming you have the SERIES package installed; but I think the fact
that it does is just an accident -- #M is only meant to work on named
functions.  [But (lambda (x) (lambda () x)) has a name in CL, anyway;
it's CONSTANTLY]

And you want a list, so

  (collect (#Mfuncall (#Mconstantly (scan-range :below 6))))
