I wrote a simple function to apply map to a float dynamic array

auto exp(float[] x) {
        auto y = x.map!(a => exp(a));
        return y;
}

However, the type of the result is MapResult!(__lambda2, float[]). It seems like some of the things that I might do to a float[], I can't do to this type, like adding them together. So I tried to adjust this by adding in a cast to float[], as in

float[] exp(float[] x) {
        auto y = x.map!(a => exp(a));
        cast(float[]) y;
        return y;
}

But I get an error that I can't convert MapResult!(__lambda2, float[]) to float[].

So I suppose I have two questions: 1) am I screwing up the cast, or is there no way to convert the MapResult to float[], 2) should I just not bother with map (I wrote an alternate, longer, version that doesn't use map but returns float[] properly).
