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).
