Here is an example code that doesn't work with the new

Attempting to run the above throws:

Error: incompatible types for `(0) : (someValue)`: `int` and
`Nullable!int`

Do you have a complete example? Because this runs without error:
```d
import std.typecons : nullable, Nullable;
import std.stdio : writeln;
void main() {
auto a = nullable(1);
auto b = Nullable!int.init;
if (!a.isNull)
writeln(a.get);
if (b.isNull)
writeln("b is null");
}
```
Steven Schveighoffer was correct, the error was caused by non
explicit `someVar;` which had to be changed to `someVar.get;`.
