As ordinary infix operators these may be negated (C<!before> and C<!after>)

+=item * Infix C<min> and C<max> may be used to select one or the other
+of their arguments. Reducing listop forms C<[min]> and C<[max]> are
+also available, as are the C<min=> and C<max=> assignment operators.
+By default C<min> and C<max> use C<cmp> semantics. As with all C<cmp>-based
+operators, this may be modified by an adverb specifying different semantics.

=item * Binary C<< => >> is no longer just a "fancy comma". It now
constructs a C<Pair> object that can, among other things, be used to
pass named arguments to functions. It provides scalar context to both sides.
