I'd like to (re)name an anonymous sub, at least for the purposes of svref_2object and it's brethren. It's cleaner to declare the sub anonymous, since it doesn't do much, is really a method call, and I'm using the anonymous "wrap up the lexicals" feature that named subs complain about.

I've tried the local *__ANON__ = "name"; solution, but it doesn't affect svref_2object. Below is the outline of the code I want to use this in. 

use B qw(svref_2object);
use Foo::Bar;
my $self = Foo::Bar->new;

# wrap a method call in a sub
my $anon = sub { $self->mumble("blah\n") };

# pass the coderef to 
$self->grumble($anon, qw(one two three));

# ...meanwhile in Foo::Bar...
sub grumble {
   my $self = shift;
   my $anon = shift;
   my @args = @_;
   # Get the name of the sub
   my $anon_cv = svref_2object ( $anon );
   my $anon_gv = $anon_cv->GV;
   my $anon_name = $anon_gv->NAME;
   print "About to call $anon_name...\n";
   $anon->(@args);
}

Update: Added a catch for $self at the beginning of grumble.
