I'm unhappy with anything other than a base interface (Context) or 
specialised interfaces (e.g. BlockContext) being used to descibe 
parameter0 of contextualize for the IS-A proposition.  Why? K/HC/CAPI 
separation; separation of interface and impl etc.  As an advocate of the 
BlockContext (and alike) solution I have no requirement for things like 
GenericBlockContext (it was a class not an interface).

Other than that, I was fairly happy with Leo's last rollup.
