Hi!
This doesn't work:
import std.stdio;
class Foo(T)
{
T t;
this(T val)
{
t = val;
}
}
void main()
{
auto o = new Foo(5);
}
kraybourne:
Then it compiles. Is it possible to have this() figure out the type some
way?
Usually people write a small global function helper.
(Side note: What _does_ that error message mean? I don't get it.)
I think the meaning is: when a class template is not yet instantiated, it's not
The error message is saying that you are trying to use Foo as a type but
Foo is not a type, it is a template for a type.

Hm, so, something like this:
Foo!(T) newFoo(T)(T val)
{
return new

Ah, so module.Foo is really not a class, but a template? I think I get
it! Thanks!
(Is then module.Foo(int).Foo the actual class
Yes. At least as the compiler would say. It's a little odd but I believe
that is how the D Nam mangling works. I personally just think of
Foo!(Class) as the type.

Is syntactic sugar for
template Foo(T){
class Foo{ ... }
}
