Thanks for the replies.
Timons reply answers my question ... now I just have to figure out how :P

Right, right, sorry, I meant a compile time argument.
And even that, it's not clear what arr[].foo means. Maybe a lazy
Range of that field, that is a lazy column.

This might be relatively trivial so please point me at documentation to read
if it is.
I am creating an array of Structs(is this the best thing to do) as per the
example below.

import std.stdio;
import std.string;
struct Data
