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. 
https://dlang.org/phobos/std_array.html#array

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

should work perfectly.

Unless you have a good reason, use a slice and not a static array:

     double[] result;

The result of std.array.array will be a slice anyway.

Why would I need to use a slice instead of a static array? I'm 
using a static array in this instance because I have and 
underlying 3d vector with double[3] as its base type

In that case, maybe this untested code

double[3] result;

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