So I have this immutable array with user defined structs but I
can not
make a copy from it.
See:
struct SwA {
string[] strings;
}
void main()
{
immutable(SwA)[] arr1;
SwA[] arr2 = arr1.dup;
}
Says:
Error: cannot implicitly convert element type immutable(SwA) to
mutable in

hi,
could anyone please explain how an array of Handlers is defined?
void Handler(int, int);
struct WData {
POINTS mouse; // Current location of the mouse
Queue clicks[WM_MOUSELAST - WM_MOUSEFIRST + 1]; //
Array to hold the coordinates of the clicks
int
try:
Handler[] mouse_handlers = new [WM_MOUSELAST - WM_MOUSEFIRST
+ 1]
or if the size is statically known:
Handler[WM_MOUSELAST - WM_MOUSEFIRST + 1] handler;

Whatever you need for what you're trying to do. If your example templates test
what you need tested, then they should work, though I confess that for
something like division, it seems to me to be overkill to

It is impossible to overload typeid typeinfo.

What do you mean: to parametrize class by Typeinfo?
class A { }
A!TypeInfo var;
If you mean this, than how it can help?
It would be well if I could create object that inherits class
with this typeinfo.
I have double dispatcher:
template Dispatcher(R)
{
R execute(Left,Right)(R delegate(Left,Right) f,Object
left,Object right)
{
return f(cast(Left)left,cast(Right)right);
}
struct Dispatcher
{
private R

I don't mean to be splitting hairs here, well maybe I do, but
D clearly makes the string type to be immutable(char)[]. That's
fine, but the std.string is all about char[] or mutable character
arrays.
So now, whenever I see a reference to the string, I have to ask
myself: do they mean the

Huh?

In any case, though, separately initializing every member of an
array is
silly. That's what a loop is for. That, or a memcpy from an
immutable
copy of .init.
I think that the reasoning behind DMD's implementation is that
for small structs, writing out the instructions is more efficient
