+=head2 C<-d:-foo> calls C<Devel::foo::unimport>
+
+The syntax C<-dI<B<:>foo>> was extended in 5.6.1 to make C<-dI<:fooB<=bar>>>
+equivalent to C<-MDevel::foo=bar>, which expands
+internally to C<use Devel::foo 'bar';>.
+F<perl> now allows prefixing the module name with C<->, with the same
+semantics as C<-M>, I<i.e.>

+This is particularly useful to suppresses the default actions of a
+C<Devel::*> module's C<import> method whilst still loading it for debugging.

+C<?PATTERN?> (without the initial m) has been deprecated and now produces
+a warning.

+
+The C<sv_compile_2op> is now deprecated, and will be removed. Searches suggest
+that nothing on CPAN is using it, so this should have zero impact.

+It attempted to provide an API to compile code down to an optree, but failed
+to bind correctly to lexicals in the enclosing scope. It's not possible to
+fix this problem within the constraints of its parameters and return value.

+C<BEGIN {require 5.12.0}> now behaves as documented, rather than behaving

+C<use strict; use warnings;> behaviour, which only C<use> was documented to
