;;; Further optimizations will turn (progn (list 1 2 3) 'foo) into 'foo.
;;; Some of these functions have the side effect of allocating memory
;;; and it would be incorrect to replace two calls with one.
;;; But we don't try to do those kinds of optimizations,
;;; so it is safe to list such functions here.
;;; Some of these functions return values that depend on environment
;;; state, so that constant folding them would be wrong,
;;; but we don't do constant folding based on this list.
;;; I wonder if I missed any :-\)
