What's wrong with D's templates?

[Tim Matthews]

In a reddit reply: "The concept of templates in D is exactly the same as 
in C++. There are minor technical differences, syntactic differences, 
but it is essentially the same thing. I think that's understandable 
since Digital Mars had a C++ compiler."

I have never touched ada but I doubt it is really has that much that 
can't be done in D. I thought most (if not all) the problems with C++ 
were absent in D as this summary of the most common ones points out

Your thoughts?
