    -   Added support for generics.  Created true generic containers.
    -   Made functions "first class" objects, implemented support for storing 
        functions in variables and "oper call", permitting the creation of 
        functors.
    -   Implemented the Platform Dependent Numeric Types and made them work 
        according to spec in all contexts.

    -   Added support for exception handling, converted the library to use 
        exceptions instead of the crack.exp.error module.

        array[int] a = [1, 2, 3];
    -   Improved string interpolation, added calls to enter() and leave() and
        made it a true expression returning the return value of leave() or the 
        target object if leave() is undefined.  Implemented a StringFormatter 
        variation that can be used in an expression context.
    -   Added the "encoding" annotation, allowing users to declare a script's
