    The D newsgroup with the most activity in it is at news.digitalmars.com.

    D already has standard library modules for zip and regular expressions.

    While it is fairly easy to convert C code to D, it is harder to convert C++.
    The main difficulty is that a very large part of the design of C++ classes
    involves dealing with memory management. Most of this becomes a non-issue in
    D, but there can remain subtle dependencies in the code on those memory
    management features.

    That said, it is a lot easier for D and C++ to interoperate than Java and
    C++. If your C++ code has a C API for it, then it is trivial to access from
    D because D fully supports the C binary API.
