Why I chose D over Ada and Eiffel

This is the statement which throws me. Templates are generic, 
there is this feature called "generics" which is an 
implementation to provide generic functions/classes (D does not 
have). But the concept of making things generic is perfectly 
achievable with templates.

Since I don't know Eiffel I don't know the exact approach to 
generics you're interested in, but D provides Templates to handle 
generics.

D also provides Interfaces and Inheritance for polymorphism, 
which may be what is of interest to you, but those aren't 
generics.

I hope D does what you want well enough, but which how you talk 
of generics I just don't know what you mean. And I don't write 
this as an attack, only to try and explain my confusion. (maybe 
others can correct my understanding).
