Why does only 'local' work on typeglobs and not 'my'

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Why can't you do something like this?

opendir(DIR,"/etc")|| die "ERROR_MSG:$!\n";
foo(*DIR);

sub foo{
  my (*ETC) = $_[0];

  while(<ETC>){
    print;
  }
}

why does it have to be local?
