I find I'm undefining variables my assigning an
unitialized variable to defined value to make it
undefined (as exemplified below).
Is there a better way to do this?

my $k;
for($i = 0; $i < $c; $i++){
  if ( defined $k ){
      print $x[$k];
      my $t; # intentionally undefined
      $k = $t; # undefine $k
   } else {
      $k = $i;
   } 
}     
undef $k;

see 'perldoc -f undef'
