Put like that, it becomes obvious how much of the generic stuff can be 
done with Interfaces.

Even with the STL, all the stuff that trickles through "my custom made 
procedures and functions" needs certain properties. C++ did a good job 
of integrating the fundamental data types and structures to this.

With anything that's objects, D can already be very powerful when one 
combines well factored interfaces with a solid set of orthogonal (not 
necessarily member-) functions.

I love D!
