Looks great, but this doesn't work if the method expects parameters. For instance: 

package Obj;

sub new {
  my $class=shift;
  my $self={ x => 'uh' };
  bless $self, $class;
}

sub howl {
  my ($self,$arg)=@_;
  print($self->{x}," $arg\n");
}

package main;

sub mname { 'howl' }

my $x=Obj->new();
$x->howl('oh');
$x->can(mname)->('ah');

The reason is that can() returns only a reference to the method, but the object ($x) is lost on the way. A workaround would be 
$x->can(mname)->($x,'ah');

[download]
but this is ugly, since it requires us to mention the object twice.
