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();
}

core.exception.AssertError@.dvm/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.

fix Issue 11730 - associative array with Nullable!SysTime values: Called `get'
on null Nullable!SysTime

When I fixed bug 6178, I internally used `cast(void)exp)` to suppress
unexpected "has no side effect" error.

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.
