Well, if D wasn't OO, I'd say it's some way to provide exactly that, 
e.g. the scripting language Lua does it that way: if it can't find a 
member in a table, it looks in another one specified similarly to this 
opDot way. That provides some kind of "inheritance".

But I can't currently imagine any way to use this either.
