Given the recent introduction of lifetimes (#642), the next thing is to extend this to allow lifetime parameters on named types. For example, something like this:

type Mutex<l> is {
   &l:int data
}

Here, the Mutex record is parameterised with the lifetime variable l.

In principle, I don't believe this extension is too challenging...

Fix for duplicate case conditions #648
This is not a complete fix for spotting duplicate case conditions.  This
is because a complete fix requires a subsequent compiler phase (or
something).  However, it does some simple stuff at the parser level.
