Current applications include:
* Non-intrusive dynamic polymorphism - interfaces can often be used in place of abstract base classes, and are sometimes much faster. * Dynamic inheritance - allows function calls to be forwarded automatically to an object specified at runtime.
The dynamic inheritance is what would be useful, IMO, for compilers. During different phases of the translation, the nodes in the AST can be "decorated" with different attributes and methods which modify those attributes in a way dependent on attributes in other nodes in the AST. An example of this, used to calculate the first and follow sets of a grammar, is at: http://cvs.sourceforge.net/viewcvs.py/boost-sandbox/boost-sandbox/boost/gram... Would you have the time and inclination to outline the advantages of http://www.kangaroologic.com/interfaces/ vs. that in the sandbox at: http://cvs.sourceforge.net/viewcvs.py/boost-sandbox/boost-sandbox/boost/dyn_... ?
