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=...").
This module prototypes the Perl 6 'exported' and 'exportable' traits
in Perl 5.
Instead of messing around with @EXPORT arrays, you just declare which subs
are to be exported (or are exportable on request) as part of those subs.
For example:
sub foo is exported { # by default
...
}
sub bar is exportable { # on request
...
}
