As of DMD 2.109.1, the following program fails to compile:

---
void main()
{
    __vector(int[4])[] a, b;
    auto result = a < b;
}
---

The error message is:

---

expression `r` of type `const(__vector(int[4]))` does not have a boolean value
/usr/include/dmd/druntime/import/core/internal/array/comparison.d(77): Error:
