The recent fixes regarding array covariance had some side-effects:

void main(){
    auto a = [new Object()];
    auto b = [new Exception("")];
    auto y = a~b; // error
}

This code should still work, even though Exception[] does not implicitly
convert to Object[] anymore. (the code works if a is declared const)
