Hi,

Is there a way to declare a class field 'auto'? I have a problem when I
try to 'promote' a variable to a field.

import std.csv;
import std.typecons;

class Test {
     this() {
         auto text = "Joe,Carpenter,300000\nFred,Blacksmith,400000\r\n";
                 auto reader = csvReader!(Tuple!(string, string,
int))(text); // how to make this a field?
     }
}

csvReader returns a private type so I can't specify the type explicitly.

Thanks,

You have two options.
a) parse and store into your own data structure.
b) use std.traits ReturnType to get the type to declare.
