As a total beginner I am feeling a bit not comfortable with
basic operations in AA.
First even I am very happy we have pointers but using pointers
in a common operation like this IMHO makes the language a bit
not safe.

Let's say I'm processing MB of data, I'm lazily iterating over
the incoming lines storing data in an associative array. I don't
want to copy unless I have to.
Contrived example follows:

- DMD64 D Compiler v2.069.2 on Linux.
- LDC 0.16.1 (DMD v2.067.1, LLVM 3.7.0)
So if it works on windows I guess it's a problem with

Is there an idiomatic way to do:
int[] numbers = [0, 1, 2, 3];
assert(adjacent_diff(numbers) == [1, 1, 1]);
I can't find something useful in the std library.

That's neat. Thx guys :)

Looks like a bug to me, for sure.
In the mean-time you may be able to use some pragma(mangle,
...) hacks to force the compiler to emit the right symbols.
Thx John,
extern(C++, A.B) {
struct Type {}
Consider the following foo.cpp
namespace A {
namespace B {
struct Type {};
int foo(Type unused){ return 42; }
}
}
Compile it : g++ foo.cpp -c -o foo.o
Then the following main.d
extern(C++, A.B) {
struct Type {}
int foo(Type unused);
}
void main() {
foo(Type());
}
Compile it : dmd
That's what I thought.
I reported this bug a while ago but it didn't get a lot of
attention.
