That's definitely a bug. Why should a declaration call opAssign?

Exactly. And, BTW, code
X x;
x = 0;
is correctly detected as a null dereference at compile time.

2x? Hardly, IMHO.

Actually my implementation is rather silly now that I've looked at it again. :)
I should have taken advantage of ranges. E.g. I could use stride() to
skip every Nth element and I could use cycle() to create a circular
buffer. I'll give this a shot soon.

Hi,
You can "disguise" method calls into variables by using the @property tag.
interface Sizeable
{
// Getter
@property int size();
// Setter
@property int size(int s);
}
class A : Sizeable
{
int m_size;
public:
this()
{
}
@property int size() { return m_s
I like the possibility of abandoning () in function calls in D, so we
can firstly make attribute public and then if implementation changes,
smoothly change it into function:
call:
auto a = new A();
writeln("Size is " +a.size);
auto b = new B();
writeln("Size is " +b.size);
class A {
publi
I'm not sure your wrapping will work with kernel32.dll, but in general
here are a few tips:
- most functions in the windows API use the __stdcall calling convention
in C/C++, which translates to D as "extern(Windows)"
- this will usually add the number of bytes passed on the stack as a
"@NN"
