[...] You can make an array of arrays from those with the
following syntax:
auto arrayOfArrays = [ keys, values ];
Then I wrote a more general program after this first one:
I really like the generic methods. Because we can use enums for
field names; e.g:
```d
import std;
void main()
{
enum {
key = "productCode",
val = "priceDolar"
}
auto makeTestTuple(int i)
{
return tuple!(key, val)((i * 2).to!string,
(double(i) / 10).to!string);
}
auto memberTuple(string member, T)(T tuples)
{
return mixin("tuples." ~ member);
}
auto tuples = 1.iota(10)
.map!makeTestTuple
.array;
string[string] myList;
foreach(t; tuples)
{
const keys = memberTuple!key(t);
myList[keys] = memberTuple!val(t);
keys.writeln(": ", myList[keys]);
}
