Detailed Description

Defines the eval::val class and associated exceptions.

Note that the eval::val class is defined within namespace eval::detail. A typedef is used to bring it into the eval namespace. (Doing so enables one to define val's friend functions within the eval::detail namespace, which otherwise does not appear to be easy.)
