+Regular expression pattern matching of things like C<qr/[^I<a>]/> is
+significantly sped up, where I<a> is any ASCII character.  Which classes

+Perl's build and testing process on Mac OS X for C<-Duseshrplib>

+
+SIP prevents binaries in F</bin> (and a few other places) being passed
+the C<DYLD_LIBRARY_PATH> environment variable.  For our purposes this
+prevents C<DYLD_LIBRARY_PATH> from being passed to the shell, which
+prevents that variable being passed to the testing or build process,
+so running C<perl> couldn't find F<libperl.dylib>.
+
+To workaround that, the initial build of the F<perl> executable
+expects to find F<libperl.dylib> in the build directory, and the
+library path is then adjusted during installation to point to the
+installed library.
