Ah, that is a nice way of doing things. And I see it is in the Request
chapter on exactly what I'm asking about, the pass-through login feature.
(See, that's what you get for having a whole bunch of different docs! Some
will be out of date; I was looking at the Authentication how-to.)

However, there seems to be a problem, which is that request.path only
contains the URL, without the parameters. And looking at the code, that
seems to be what it is meant to contain--isn't this, in A::MVC's
parse_location, meant to strip the params out of the $r->{path} entirely?

  $self->{path} =~ s/^($loc)?\///;

Thus [% request.path %] won't actually contain the full path, and this
suggestion in the pass-through login thing won't work.
