Detailed Description

Exception thrown on attempts to use a context not matching what the unit expects. Type-erased wrapper around an instance of a parsing unit's context type.

This stores a reference to the instance, along with shallow copy semantics. That means that units using copies of a particular instance of this class will all share the same context.
