Detailed Description

Removes the ability to use an assignment operation on derived classes.

In some cases, it is not desirable to be able to assign onto an existing instance of a class while still allowing the ability to construct copies (see psystem::not_copyable to prevent both). An "immutable" class is one such instance. Classes may declare themselves with psystem::not_assignable as their base to get this functionality. This class will not add any overhead at run-time.

Note

This can be cirucumvented, of course, by simply overloading operator=().
