Aspect::Pointcut::Wantarray - A pointcut for the run-time wantarray context

  use Aspect;
  
  # High-level creation
  my $pointcut1 = wantlist | wantscalar | wantvoid;
  
  # Manual creation
  my $pointcut2 = Padre::Pointcut::Or->new(
    Padre::Pointcut::Wantarray->new( 1 ),     # List
    Padre::Pointcut::Wantarray->new( 0 ),     # Scalar
    Padre::Pointcut::Wantarray->new( undef ), # Void
  );

The "Aspect::Pointcut::Wantarray" pointcut allows the creation of aspects that only trap calls made in a particular calling context (list, scalar or void).
