(alexandria.0.dev:ends-with-subseq suffix sequence &key (test #'eql))
Function: Test whether SEQUENCE ends with SUFFIX. In other words: return true if the last (length SUFFIX) elements of SEQUENCE are equal to SUFFIX.
  
(alexandria.0.dev:starts-with-subseq prefix sequence &rest args &key
 (return-suffix nil) &allow-other-keys)
Function: Test whether the first elements of SEQUENCE are the same (as per TEST) as the elements of PREFIX. If RETURN-SUFFIX is T the functions returns, as a second value, a displaced array pointing to the sequence after PREFIX.
