in reply to strict, debug and global variables

is there a way to declare them when the file is 'require'd

Yes, there is, if you can use() the module. It requires that you write your own &import routine. 

  use vars ();
  sub import {
    my $pkg = caller;
    no strict 'vars';
    vars::->import(map { /(.)(.*)/; "$1$pkg\::$2" } qw/ $var1 $var2 $e
+tc /);
  }

If you export things with the Exporter module you need to handle that: 
  use vars ();
  sub import {
    __PACKAGE__->export_to_level(1, @_);

    my $pkg = caller;
    no strict 'vars';
    vars::->import(map { /(.)(.*)/; "$1$pkg\::$2" } qw/ $var1 $var2 $e
+tc /);
  }

Exporter does this for you if you export the variables, so that's a much easier way...
