Screw that.

sub write_file {
  my ($self, $c, $filename) = @_;
  my $data = $self->render($c, ...); # look at how process calls render
  <write data>
}

then do:

$c->view('Foo')->write_file($c, $filename);

Having to pass $c along like that is a little bit annoying, but this approach
is -way- simpler.

Of course if you were feeling truly insane you could do

  $self->template->{OUTPUT} = sub { <capture $filename here> };
  $self->render(...);

but I don't really see that it would gain you anything.

*wonders if write_file should be a role that applies to any view that supplies
render* ...
