to trigger/signal a rebuild for the transition 5.8.8 -> 5.10.0.
The list of packages is computed by finding all packages which end
up having either of PERL5_USE_PACKLIST, BUILDLINK_API_DEPENDS.perl,
or PERL5_PACKLIST defined in their make setup (tested via
"make show-vars VARNAMES=...").
IO provides a simple mechanism to load several of the IO modules
in one go. The IO modules belonging to the core are:
IO::Handle
IO::Seekable
IO::File
IO::Pipe
IO::Socket
IO::Dir
IO::Select
IO::Poll
Note that these modules should be loaded via
use IO qw(Handle File); # etc.
and not via the deprecated method
use IO; # DEPRECATED
