Many handlers in the same module

[Colin Wetherbee]

Greetings.

In order to have many handlers in a file, I've put the following lines 
and other, similar lines in my virtual host configuration:

PerlAccessHandler JetSet::Handler->AccessHandler
PerlResponseHandler JetSet::Handler->ResponseHandler

Then, my handlers look like this:

sub ResponseHandler
{
  my (undef, $r) = @_;
  # ...
}

This seems to work well enough, but just today, I thought there might be 
some reason to not do this.  I searched through the documentation and 
couldn't find anything, but it's still nagging me.

Is there anything inherently Bad about doing this?

I think the undef $self is bugging me the most, but I don't know why 
this would cause any problems.

Thanks.

Colin
