           Summary: Static array of `float`s is implicitly initializable
                    from array of `double`s

It is rewritten as for `cast(float[])`:
---
void main()
{
    double[3] d3;
    float[3] f3 = d3; // or `= new double[3]`
}
---

And correctly fails in runtime with:
---
object.Error: lengths don't match for array copy, 3 = 6
----

This was discovered from Issue 9429 an is major as e.g. this will compile and
fail in RT with same error as above:
---
float[3] arr = [1.0, 2.0, 3.0].dup;
---

P.S.
Want to laugh? There is Issue 6489. Looks like its author applied some magic to
force dmd partially accept what he wants. As always magic worked bed. Thus we
all prefer science now. )
