Insted it should throw if range with non default contructable elements is
exhausted:
---
import std.exception, std.range;

void main()
{
    static struct S { @disable this(); }
    static assert(__traits(compiles, zip((S[5]).init[]))); // assert fails
    // This is assumed to compile and pass:
    assertThrown(zip(StoppingPolicy.longest, cast(S[]) null, new
int[1]).front);
}
