except that i wouldn't do the 'brains dance' inside the template but  
in the view class.

i've adopted the practice of only passing out dictionaries or adapted  
objects into my templates.

the `getLazyEntries` method is an implementation detail that should  
be abstracted from the template.

without looking at the current interfaces i would postulate having a  
`getEntries` method for `IWeblogView` that simply returns instances  
that provide `IWeblogEntry` -- that's all the template needs to know.

bingo! (IMHO)...
