I Agree. Looking at the Groovy link from Christophe I noticed their Safe
Navigation Operator ?.
Basicly it returns the final value in a dereference chain or null if any
objects in the chain are null:
// a is null if user or address or street is null. No exception thrown.
auto a = user?.address?.street;
But what would the static type of "a" be? I tried this:
class Foo {}
void main ()
{
auto a = true ? new Foo : new Object;
static assert (is(typeof(a) == Object));
}
And it passes. You loose static typing.
How would the type of "a" be resolved if there's a field/method that
returns a value type in the chain? Compile time error?
