I have code such as

    if (my $user = $c->req->header('X-Proxy-REMOTE-USER')) {

	$c->engine->env({ REMOTE_USER => $user });

	$c->authenticate({});

    }

which works, but I get a warning "env as a writer is deprecated, you
probably need to upgrade Catalyst::Engine::PSGI".

I'm unsure what to do here. Should I write a Plack::Middleware plugin that
translates the X-Proxy-REMOTE_USER header to an env->{REMOTE_USER}?
