Looks like this was fixed in 2.064.
What version of the compiler are you using?

Hi,
is there any document or text describing forward references?
It is kinda strange, i implemented a list structure which is
kinda like this:
struct list(T)

struct node

T val;
node* next;
node* prev;
}
node* head;
node* last;

Hello,
I want to convert from ints implicit to a struct type, so for
example:
struct use
{
int x;
int toInt()
{
return x;
}
use fromInt(int v)
{
return use(v);
}
alias toInt this; // implicit
Hello,
is there anyway to do something like this:
mixin template foo( exp)
{
static if(__traits(compiles, exp))exp;
}
Thanks :)
Sry i know i asked it already in IRC:
Are rvalue references already solved with auto ref?
https://p0nce.github.io/d-idioms/#Rvalue-references:-Understanding-auto-ref-and-then-not-using-it
Says rvalues are moved!
The other solution seems not so practical.
Is any solution to them intended, or

The network should simply add the input values together, so [1,2]

If i declare the parameter as ref i, then there shouldnt be any

Hey there:)
i want to know whether the following is somehow possible:
structs dont have default constructors, i know so:
struct A

this(int i){field = getDataFromFile("file.txt");}
}
A instance = A(0);
