Am I missing something obvious in Template Toolkit 2?

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

I just installed Template Toolkit 2 from CPAN. Now I noticed that my $vars->{'template'} is deleted after processing.

when I change it's name from 'template' to 'input', everyything is fine. Is there something special about that variable? Is is documented or a bug?

Here a short excerpt from my debug session:

  DB<1> c 35
main::(./build:35):     $tt2->process( $vars->{'template'}, $vars, $va
+rs->{'output'});
  DB<2> x $vars
0  HASH(0x12e40)
   'build' => 9
   'file' => ARRAY(0x1a23598)
      0  'manifest.php'
      1  'LICENSE.txt'
   'output' => 'manifest.php'
   'revision' => 0
   'template' => 'manifest.tt2'
   'version' => 0.3
  DB<3> n
main::(./build:37):     my $pckg= new Archive::Zip();
  DB<3> x $vars
0  HASH(0x12e40)
   'build' => 9
   'file' => ARRAY(0x1a23598)
      0  'manifest.php'
      1  'LICENSE.txt'
   'output' => 'manifest.php'
   'revision' => 0
   'version' => 0.3
  DB<4> q

See? 'template' => 'manifest.tt2' is gone.
