Untested, but it is essentially:
class ExampleWidget(Widget):
params = ["items"]
template = """
<p py:content="'<br/>'.join(render(item) for item in items)">
</p>
"""
example_widget = ExampleWidget()
A big plus for me is that, as I am planning to later add some flashy
AJAX stuff in, when that time comes I can just pop the jaavscript
into my widget, change the template slightly, and it all still works
fine.
