It is unclear from the specs if null should be exact matched against nullable types during IFTI. Now it works only for void*. class C { } void foo(T)(T x, C c) // C - a nullable type { } void main() { foo(1, null); // fails foo(1, cast(C)null); // ok } Is it by design? |

I think it is a bug. This might be relevant: http://d.puremagic.com/issues/show_bug.cgi?id=2389 |

This might be relevant: http://d.puremagic.com/issues/show_bug.cgi?id=2389 Not a big issue, but I felt like filing it anyway http://d.puremagic.com/issues/show_bug.cgi?id=2394 |
