 Hyper Operators include C<«> and C<»>, with their ASCII variants C«<<»
-and C«>>». They apply a given operator enclosed by C<«> and C<»> to one or two
+and C«>>». They apply a given operator enclosed (or preceded or followed, in the case of unary operators) by C<«> and/or C<»> to one or two
 lists, returning the resulting list, with the pointy part of C<«> or C<»> aimed at the shorter list. Single elements are turned to a list, so they can be used too. If one of
 the lists is shorter than the other, the operator will cycle over the shorter
 list until all elements of the longer list are processed.
