D doesn't have macros per se. However, template metaprogramming 
and mixins can replace them in many cases.

Which particular form of pattern matching do you have in mind? 
You won't get all the way to Haskell (or even Prolog) levels of 
functionality in a generic way, but for limited use cases, it is 
definitely possible.
