+=item Regexp::Keep internalized

+The functionality of Jeff Pinyan's module Regexp::Keep has been added to
+the core. You can now use in regular expressions the special escape C<\K>
+as a way to do something like floating length positive lookbehind. It is
+also useful in substitutions like:
+
+  s/(foo)bar/$1/g
+
+that can now be converted to
+
+  s/foo\Kbar//g
+
+which is much more efficient.
