There are some subtle differences:

  1. Unless the declaration of some_subroutine was moved up, there would be a warning about an undefined subroutine. The assignment runs after the declaration (which happens on compile-time) and so no warning.
  2. if the code were using anonymous subroutines as in 
    my $coderef = sub {
    #...do something with @_...
    return ($value1, $value2);
};

    there would be no entry on the current package/namespace/stash. That makes a really private code.
