Bug 11730 – associative array with Nullable!SysTime values: Called `get' on null Nullable!SysTime.

The following program throws on D 2.064.2: import std.datetime; import std.typecons; void main() { Nullable!SysTime[string] map; map["foo"] = Nullable!SysTime(); } [email protected]/compilers/dmd-2.064.2/bin/../src/phobos/std/typecons.d(1233): Called `get' on null Nullable!SysTime. It works on D 2.063.2.

But, `CastExp` always try to resolve alias this of its operand to find most matching type to `void` via `Expression::castTo`. It should be disabled. https://github.com/D-Programming-Language/dmd/commit/e6ffe6e50ffda444b4f4ec086f8149c55d74c933 Merge pull request #2961 from 9rnsr/fix11730 [REG2.064] Issue 11730 - associative array with Nullable!SysTime values: Called `get' on null Nullable!SysTime
