Timon Gehr:
The notation 'T?' is normally used for a nullable type.
Right. that's why I have suggested a trailing "@":

------------------------
Namespace:
void foo(Object? o) {
// do something with o
}
[/code]
will convert into
[code]
void foo(Object o, string filename = __FILE__, uint line =
__LINE__) in {
if (o is null) throw new Exception("Object is null.", filename,
line);
} body {
// do something with o
}
[/code]
Object@ is a type, so if you write:
void foo(Object@ o) {...
It means the compiler statically refuses you to give a nullable
type to foo. So inside foo there is no need for a run time test.
Good work :-)
