=head2 Add C<package NAME VERSION> syntax
- This patch adds support for setting the $VERSION of a namespace
- when the namespace is declared with 'package'. It eliminates the
- need for 'our $VERSION = ...' and similar constructs. E.g.
+This new syntax allows a module author to set the $VERSION of a namespace
+when the namespace is declared with 'package'. It eliminates the need

package Foo::Bar 1.23;
# $Foo::Bar::VERSION == 1.23

+C<$VERSION> is set at compile time

- * Alpha versions with underscores do not need to be quoted; static

- will remove underscores as it does for all numeric literals
+Eliminates C<$VERSION = ...> and C<eval $VERSION> clutter
- During development of this, there was discussion on #corehackers and
- elsewhere that this should also allow other metadata to be set such as
- "status" (stable/alpha) or "author/authority". On reflection, those
- metadata are not very well defined yet and likely should never be
- encoded into Perl core parsing so they can be freely changed in the
- future. (They could perhaps be achieved via a comment on the same line
- as 'package NAME VERSION'.)
+=item *
- Version numbers, however, already have a very specific definition and
- use defined in the core through 'use NAME VERSION'. This patch merely
- provides appropriate symmetry for setting $VERSION with the exact same
- parsing and semantics as 'use'.
+As it requires VERSION to be a numeric literal or v-string
+literal, it can be statically parsed by toolchain modules
+without C<eval> the way MM-E<gt>parse_version does for C<$VERSION = ...>
- It does not break old code with only 'package NAME', but code that
- uses 'package NAME VERSION' will need to be restricted to perl 5.11.X.
- This is analogous to the change to open() from two-args to three-args.
- Users requiring the latest Perl will benefit, and perhaps N years from
- now it will become standard practice when Perl 5.12 is targeted the
- way that 5.6 is today.
+=item *
- The patch does not prevent 'package NAME VERSION' from being used
- multiple times for the same package with different version numbers, but
- nothing prevents $VERSION from being modified arbitrarily at runtime,
- either, so I see no urgen reason to add limitations or warnings so
- long as Perl uses a global $VERSION variable for package version
- numbers.
+Alpha versions with underscores do not need to be quoted; static
+parsing will preserve the underscore, but during compilation, Perl
+will remove underscores as it does for all numeric literals
- I am posting this patch to the p5p list for discussion and review. If
- there seems to be general assent (or lack of dissent), I will go ahead
- and commit the patch to blead.
