I have struck a snag with the documentation.

says....
use Apache2::Connection ();
use Apache2::RequestRec ();
my $c = $r->connection;
What is $r?
I am missing something obvious, what is the context here I do not get?
Hi.
Maybe you should start here :
https://perl.apache.org/docs/2.0/user/handlers/intro.html#What_are_Handlers_
$r is the "current request object". How you obtain it varies a bit depending on where you
are (in a mod_perl handler, in a cgi-bin script etc..).
Usually, you'll be in some kind of handler() sub, and the usual idiom then is
just
sub handler {
my $r = shift;
..
}
as the request object is the first and usually the only parameter passed in
such a sub/method.
It is also usually the starting point for everything else in mod_perl.
If you are a real beginner, a recommendation : persist, you'll soon get the hang of it,
and it's worth the effort. Perl is fun; Apache + mod_perl is *a lot* of fun, and
incredibly powerful.
