Branch: CURRENT, Version: 0.29nb1, Package name: p5-Want-0.29nb1, Maintainer: pkgsrc-users

This Perl 5 module generalises the mechanism of the wantarray

    - perl 5.23.8 breaks the hack we were using to implement double_return.

    This patch from David Mitchell fixes it. See \ 
https://rt.cpan.org/Ticket/Display.html?id=112226

    David wrote:

    > Running with a debugging perl-5.23.8 will show assertion failures in \ 
the Want test suite. It's because PL_comppad/PL_curpad save/restore is now done \ 
by the context stack / cx_popsub() rather than as previously on the savestack / \ 
LEAVE.

    > This stops the double_return() 'convert CXt_SUB to CXt_NULL' hack from \ 
working properly, as PL_comppad is no longer restored when transitioning from \ 
the inner to outer sub. The attached patch substitutes one evil hack for \ 
another: it keeps the CXt_SUB context stack entry, but sets its retop field to \ 
point to the return op again (rather than its caller) so that the return op gets \ 
called twice (with a bit of markstack hackery to ensure there are two marks for \ 
the two returns to pop).

    > rreturn and lnoreturn are also a bit under-tested. In particular, there \ 
are no tests for rreturn in list context. I added such a test, but more need \ 
adding.

    - Restore compatibility with certain older perl versions (5.10 and 5.12)

      It seems that �𦯷TTRS: lvalue�� doesn�脌 work with older perls, \ 
but that you can
      forward-declare the method in Perl code with the :lvalue attribute with \ 
the same
      effect.

      This version of Want is still broken with perl 5.8, for reasons I \ 
haven�脌 investigated.

    - There is a new experimental option in bleadperl under which one ought not \ 
to use
      the op_sibling field directly. Quoting from perlguts.pod:

        Starting in version 5.21.2, perls built with the experimental
        define C<-DPERL_OP_PARENT> add an extra boolean flag for each op,
        C<op_moresib>.  When not set, this indicates that this is the last \ 
op in an
        C<OpSIBLING> chain. This frees up the C<op_sibling> field on \ 
the last
        sibling to point back to the parent op. Under this build, that field is
        also renamed C<op_sibparent> to reflect its joint role. The macro
        C<OpSIBLING(o)> wraps this special behaviour, and always returns \ 
NULL on
        the last sibling.  With this build the C<op_parent(o)> function can be
        used to find the parent of any op. Thus for forward compatibility, you
        should always use the C<OpSIBLING(o)> macro rather than accessing
        C<op_sibling> directly.

      Thanks to Reini Urban for the patch.

    - Add support for the new OP_MULTIDEREF
      Perl has a new op, added as a performance optimisation
      in fedf30e1c349130b23648c022f5f3cb4ad7928f3, to
      represent a sequence of array/hash dereferences. This
      patch adds support for the new op.

Log message:
Bump for perl-5.20.0.
Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.
