NAME
    B::Flags - Friendlier flags for B

SYNOPSIS
      use B::Flags;
      # some ops
      print B::main_root->flagspv;
      print B::main_root->privatepv;
      print $some_b_sv_object->flagspv;

DESCRIPTION
    Stringification of flags.

    By default, "$foo->flags" when passed an object in the "B" class will
    produce a relatively meaningless number, which one would need to grovel
    through the Perl source code in order to do anything useful with. This
    module adds "flagspv" to the SV and op classes and "privatepv" to the op
    classes, which makes them easier to understand.

METHODS
    OP->flagspv
        Returns stringification of the OP flags.

        Adds now SIBLING to abstract the new LASTSIB/MORESIB flags since
        5.21/5.22 and the old "op_sibling" pointer. Since 5.22 missing the
        SIBLING flags indicates a PARENT at the "op_sibparent" pointer, with
        -DPERL_OP_PARENT.

    OP->privatepv
        Returns stringification of the OP private flags.

    SV->flagspv [type]
        Returns stringification of the SV flags.

        With the optional type only the flags for the given SvTYPE are used.
        type 0 is for the SvFLAGS only. This way you can seperate between
        sv->FLAGS and specialized AvFLAGS, GvFLAGS, CvFLAGS, ... in seperate
        struct fields.

        Note that only the names of bitmasked SV and OP flags are returned,
        not pseudo flags, like TAINTED, which is stored as magic.
