Right. It's a tool for frameworks/template libraries to implement internal
SafeString/Markup/whatever objects, not for application/library authors to make
HTML representations of their model objects. If a Jinja2 user is viewing a
Markup object in IPython, they want to see "Markup(u'<p>foo</p>')", not an
HTML-formatted "foo". The HTMLFormatter's behavior is undesirable, and I think
this is a good reason to avoid using __html__, at least.
