hash indicates whether you are getting back a singular value (a
scalar) or a plural one (a list).
+=head3 Key/value hash slices
+
+A key/value hash slice operation is variant of slice operation that
+return list of key/value pairs rather than just values:
+
+ %sub = %h{'foo', 'bar'}; # key/value hash slice
+
+However, result of such slice can not be localized, deleted or used
+in assignment. Otherwise very much consistent with hash slices.
+
+=head3 Index/value array slices
+
+Like for hash the following returns list of pairs, but with
+index/value pairs:
+
+ @list = %a[3,4,5];
