Hi all,
How can I change the following to a more D-like approach by 
using UFCS?

double[3] result;
Json json = res.readJson;
for(int i = 0; i < json.length; i++){
    result[i] = json[i].to!double;
}

I'd prefer to do something like:

result = res.readJson[].map!(to!double);

Use std.array.array (alias: std.range.array) to make the range 
returned my map!(to!double) into an array.
Note that the result of map isn't actually evaluated until it is 
iterated. std.array.array will iterate and collect.

    result = res.readJson[].map!(to!double).array;

should work perfectly.
