It would be quite hard to do this with the layout rule, since the nature 
of the layout rule is that you don't know if the definition is complete 
until you read the next line. So you don't know whether or not to 
execute it yet...

With explicit notation {}, and friends, I don't see a technical reason 
not to. I just write long definitions though.
