[Issue 16047] Range violation in setting multi-dimensional AA entries
https://issues.dlang.org/show_bug.cgi?id=16047 --- Comment #3 from FeepingCreature --- What happens here is that the complex expression for the first index forces DMD to allocate a temporary. In the course of doing so, it forgets to indicate that the temporary is for a nested assignment, and the temporary (which is a plain IndexExp, not an assignment) runs into a range error. --

Tighter repro:
struct Reassignable
{
void opAssign(Reassignable) {}
}
int s() { return 1; }
void main()
{
Reassignable[int][int] aa;
aa[0][0] = Reassignable.init;
aa[s()][0] = Reassignable.init; // range violation
}

Workaround: use `require`
aa.require(S("baz").s, null)["baz"] = SysTime.init;
