Re: Passing D reimplementation of C++ template as argument to a C++ function

Hi!
I have a D template struct that reimplements a C++ class
template with identical memory layout for a set of types that
matter to me. Now, I want to use some C++ functions and classes
that use these template instances, from D. For that, I want to
purposefully alias the D and C++ types. However, with the C++
type being templated, I don't know how to name that type in a
extern declaration in D.

```
extern(C++) extern(C++, class) struct Foo(T) {
T a, b;
}
alias FooFloat = Foo!float;
extern(C++) void bar(FooFloat f);

Deimos libzip bindings review request
Hi, I have created D bindings for [libzip](https://libzip.org/), and i think it would be nice to include these bindings in deimos, because standard [std.zip](https://dlang.org/phobos/std_zip.html) does not allow to work with large zip archives. But i am not sure if i have done it in right way. Especially legal side (licenses, authorship, etc). Thus, i thought that it could be good idea to ask community for review before publication to code.dlang.org. The project for bindings: https://gitlab.com/katyukha/dlibzip Thanks a lot for any feedback)

Thank you for your input, Adam. Real shame that there's no built-in compiler solution and probably never will be according to [1]. :( [1] https://issues.dlang.org/show_bug.cgi?id=4595 AFAIK diagnostics like that are not possible because Walter doesn't want to implement full blown dataflow analysis in the compiler since it will slow down the compilation speed of dmd Implementing such a diagnostic is equivalent, in the general case, to solving the halting problem. So even with dataflow analysis, there would always be cases where the compiler either fails to detect a potential null dereference (false negative), or detects one that can't actually happen at runtime (false positive).
