Defn does not work recursively

[JJ]

In this example:

use v6;

use Pod::To::HTML;

my $pod = q:to/END/;
=pod
=defn What is this
My I<super B<awesome>> embedded C<pod>
document!
END
say Pod::To::HTML.render($pod);

Produced HTML is:

<dt>What is this</dt>
<dd><p>My I&lt;super B&lt;awesome&gt;&gt; embedded C&lt;pod&gt; document!</p>

[JJ]

I think this is the same problem as #17. Defn is returned as text, not as a block...
