One would assume that, given an array literal of various implementations of an interface, the compiler would reduce the literal to an array of that interface. However, the following fails:

interface Inter {
}

class FooImpl : Inter {
}

class BarImpl : Inter {
}

void main()
{
    Inter[] test = [new FooImpl(), new BarImpl()];
}

with

poly.d(12): Error: cannot implicitly convert expression (new FooImpl) of type
object.Object to poly.BarImpl
poly.d(12): Error: cannot implicitly convert expression ([(__error), new
BarImpl]) of type BarImpl[] to Inter[]

This has the same cause (and fix) as issue 5498.
