It looks like %telealph and @telear are two different views of the same data. For cases like this, I'd suggest maintaining whichever one is more obvious, and building the other from it: 
  my %telealph = (
    ( map { $_ => $_ } ( 0 .. 9 ) ),
    ( map { my $d = $_; map { $_ => $d } @{ $telear[$d] } } ( 0 .. $#t
+elear )
  );
