Will the loop (foreach) run at compile time? How can I make it
work at compile time?
```
import std.csv, std.stdio;
alias Record = Tuple!(string, string, string);
immutable string[][] table;
shared static this() {
string csvText = import("file.csv");
foreach (record; csvReader!Record(csvText)) {
table ~= [record[0], record[1], record[2]];
}
}
void main() {
writeln(table):
}
```
I would do this.
```
import std;
alias Record = Tuple!(string, string, string);
static immutable string[][] table = () {
string[][] table;
string csvText = import("file.csv");
foreach (record; csvReader!Record(csvText)) {
table ~= [record[0], record[1], record[2]];
}
return table;
}();
pragma(msg, table); // Available at compile-time
void main() {
writeln(table);
}
```
And then `-J{path}` to tell the compiler where to find `file.csv`.
```
dmd -J. csv.d
```
