Yes. Because Typedef is introducing new Types, which csvReader 
doesn't know what they are,
you'll need a little workaround and cast the values yourself.

import std.csv, std.stdio, std.algorithm, std.range;

enum csvTxt = "10, 20
30, 40
50, 50";

myStuff = csvTxt.csvReader!(Tuple!(long, long))
        .map!(a => MyStuff(cast(QuestionId)a[0], cast(StudentId) a[1]))
        .array;


The .map does nothing other as getting the information out of 
the Tuple 'a' and constructing a struct of the type MyStuff.

Yes that does make sense. I could read in a POD struct and 
convert it to a typed one.

Though I was hoping for a more elegant solution... This'll have 
to do I guess.

Thanks!
