+still-in-development work leading to a Perl 5 to Perl 6 converter. To
enable it, it's necessary to pass the argument C<-Dmad> to Configure. The
obtained perl isn't binary compatible with a regular perl 5.9.4, and has
space and speed penalties; moreover not all regression tests still pass
with it. (Larry Wall, Nicholas Clark)

C<config_data> is a new utility that comes with C<Module::Build>. It
provides a command-line interface to the configuration of Perl modules
that use Module::Build's framework of configurability (that is,
-C<*::ConfigData> modules, that contain local configuration information for
+C<*::ConfigData> modules that contain local configuration information for

still use them. They come from a factorization effort: for example, many
PP functions are now shared for several ops.
Bytecode tests fail under several platforms. We are considering removing
support for byteloader and compiler before the 5.10.0 release.
