Hi all,
do you see any valid reason why the last line yields an error:
import std.typecons;
void main()
{
void* ptr1;
void* ptr2;
assert(ptr1 is null);
assert(ptr2 is null);
assert(ptr1 == ptr2);
Nullable!uint val1;
Nullable!uint val2;
assert(val1.isNull);
assert(val2.isNull);
assert(val1 == val2);
Nullable!(uint, uint.max) val3;
Nullable!(uint, uint.max) val4;
assert(val3.isNull);
assert(val4.isNull);
assert(val3 == val4);
}
The error is
core.exception.AssertError@/usr/local/opt/dmd/include/dlang/dmd/std/typecons.d(3457):
Called `get' on null Nullable!(uint,nullValue).
As I can see, this is due the lack of opEquals in the Nullable(T,
T nullValue), in contrast to Nullable(T).
