Uh, $array and $var have the same value now.  shift() removes the first
element from an array (defaulting to @_) and returns it.  The first
element of @_ is $_[0], which is $var1.

Saying

  my $var = $_[0];

is not the same as

  my $var = shift;

The first one does NOT remove the element from @_; the second one DOES.
