... as I tried adding a proper exception page to a toy project of mine  
last weekend [1], and did not get it working until I found this thread  
and put in a grok.name('index.html').

Would a grok.ExceptionView class which has a default grok.name of  
index.html be a good idea? And is there a sane way to implement this?

Groet,
Jasper
