Is this a good pattern for allocation?

The purpose of inheritance is to allow one to modify the 
allocation scheme if necessary and to have a common interface 
which looses the dependency on any standard library, D, or the 
GC. (e.g., instead of having to change new every place it occurs 
one just has to change it either in the factory or in the New 
method).

I guess you mean that I should use a template as a factory 
instead of an interface? I'll have to think about it to see what 
the pro's and con's of each are. The interface pattern should 
include the template pattern though. (after all, the interface is 
parameterized...)
