They syntax I wanted was something like:
bool func (const out Key k, const out Val v) { k =
this.key.dup; v = this.val.dup; return true; }
This works for me:
```d
template Fun(Key, Value)
{
import std.typecons;
alias Tup = Tuple!(const(Key), const(Value));
enum Fun = (Key k, Value v) => Tup(k, v);/*
auto Fun(Key k, Value v) {
return Tup(k, v);
}//*/
}
string k;
uint v;
auto res = Fun(k, v);
static assert(is(typeof(res[0]) == const(string))); // false
static assert(is(typeof(res[1]) == const(uint))); //false
```
I rewrote the code to return the enum. However, static asserts
return false. What could this cause?
P.S. Actually the code works when we don't use enum.
