Hi All,

  Was able to find on hot to store a struct in an array, but not 
able to use that array in csvReader

Program:
import std.algorithm: joiner;
import std.container.array;
import std.csv: csvReader;
import std.stdio: File, writeln;
import std.typecons: Tuple, tuple;

void main () {
auto fName = 
"C:\\Users\\bheev1\\Desktop\\Current\\Script\\Others\\Table1.csv";
auto uFile = File(fName, "r");
struct T1 { string Name; string Country; int Age; }
Array!T1 T1s;
foreach (record; 
uFile.byLineCopy().joiner("\n").csvReader!(Tuple!T1s))
writeln(record);
}

Error:
C:\D\dmd2\windows\bin\..\..\src\phobos\std\typecons.d(523): 
Error: template instance parseSpecs!(T1s) cannot use local 'T1s' 
as parameter to non-global template
  parseSpecs(Specs...)
C:\D\dmd2\windows\bin\..\..\src\phobos\std\typecons.d(635): 
Error: CTFE failed because of previous errors in injectNamedFields
