I need a function that works like the following:
T* New(T)() { return new T; }
But that also works with static arrays:
auto i = New!(int)();
auto a = New!(int[27])();
The cleanest solution I can think of is:
T* New(T)() { return (new T[1]).ptr; }
but that seems ugly. Any ideas?

It looks to me like it might be the same issue as bug# 3682:
http://d.puremagic.com/issues/show_bug.cgi?id=3682 - although I ran into it
in a different way.

Okay, does anyone know a good way to figure out where something like
this is coming from:
object.Exception: lengths don't match for array copy
All,
Does anyone know where I can get a simple example of writing a server in
D? Just a stupid little echo server would be fine. I'm trying to write
one myself, but for some reason it doesn't seem to be accepting any
connections. I figure it's something stupidly simple, but I'm just not

Well I forget the details, but it's been pointed out before
that D's cast is fundamentally broken.
You get one cast operator that hides the full set of c++
static, dynamic, const & reinterpret casts.

D2 module system has several bugs, but I can't know if the bug is in your code,

If you use a dynamic array in there somewhere, the chances of it not
working go up, I'm afraid. This doesn't leave many programs that *work*.

To perform that translation you have to do first adapt the original Java code
to D as much as possible keeping it woeking, then add unit tests to each method

I see that neither the constructor nor the postblit is called.
Apparently the bit representation is used. This has the risk of
violating struct invariants.
Is it legal?
