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.
