Issue ID: 18545
Summary: Casting away const with cast() triggers alias this,
but returns the supertype anyway
Product: D
Version: D2
Hardware: x86_64
OS: Linux
Status: NEW
Severity: normal

const Nullable!string a;
Nullable!string b = a; /* This works. */
Nullable!string c = cast() a; /* This asserts in get. */
// Alright, so I guess cast() mistakenly follows the alias this?
// No!
static assert(is(typeof(cast() a) == Nullable!string));
// It follows the alias get this in Nullable, but it returns a Nullable anyway.
// Why!!
