Sorry about the sloppy language, I was referring to the default Image string 
representation for a type.

The proposal for 'Image defines such a representation for all types (for a 
task, it is the task id and discriminants, for instance). It's not clear how 
to define 'Value usefully for such a representation (most likely it would 
not be).

In any case, it is a non-trivial problem, substantially harder than the 
matching problem for 'Image.
