Body is not strictly necessary to parse it. But it makes for a nice "anchor" 
when the in and out clauses get long.

In any case, we are currently working on getting temp destruction to work 
correctly, and after that we'll work on fixing issues with const. I think these 
are the most important things we should be working on at the moment.
