The Email::Sender::Transport::Print module has very sparse documentation. It does say you can pass a file-handle object in as the attribute "fh". Looking at other Email::Sender::Transport implementations, it appears to me that passing a hash to new with the attributes as name/value pairs is the way it's done (there's a rather startlingly complete shortage of examples of Email::Sender::Transport::Print usage on the web).

The code is:

    open (my $sm, '>> :encoding(UTF-8)', 'out.txt') or
      die "Failed to open out.txt: $!";
    $transport = Email::Sender::Transport::Print->new({
        fh => $sm,
    });

($transport is declared outside the bit quoted, but it is declared.)

When I do that, I get the error "isa check for "fh" failed: GLOB(0x806897840) is not blessed". This seems to imply that it noticed that I was in fact passing something as attribute fh, at least!

In the debugger, it seems to me that $sm, the thing passed in as the value of attribute fh, is in fact blessed.

  DB<3> x $sm
0  GLOB(0x806897840)
   -> *main::$sm
         FileHandle({*main::$sm}) => fileno(7)

I am now wondering WTF. A preliminary attempt to look at the source code of the module foundered; it appears there is none, it's generated on-the-fly using moo or something? Which I'm not familiar with, and while in theory I could study it up and then figure out for sure what's expected, that's starting to look like a large amount of work.

Ideas?
