(alexandria.0.dev:map-derangements function sequence &key (start 0) end
 (copy t))
Function: Calls FUNCTION with each derangement of the subsequence of SEQUENCE denoted by the bounding index designators START and END. Derangement is a permutation of the sequence where no element remains in place. SEQUENCE is not modified, but individual derangements are EQ to each other. Consequences are unspecified if calling FUNCTION modifies either the derangement or SEQUENCE.
