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=...").
Defines a set of symbolic constants with ordered numeric values ala C
enum types.
Now capable of creating creating ordered bitmask constants as well. See
the BITMASKS section for details.
What are they good for? Typical uses would be for giving mnemonic names
to indexes of arrays. Such arrays might be a list of months, days, or a
return value index from a function such as localtime():
use enum qw(:Months_=0 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec);
