Hi,

I am trying to use variantArray() as a data table object to hold columns each of which is an array of a specific type. I need to be able to get values from data table but I am having problems ...


import std.stdio; // i/o
import std.variant; // type variations

void main(){
  // Columns of the table
  string[] names = ["walter", "paul", "jeff", "andrie"];
  int[] age = [55, 62, 27, 52];
  string[] language = ["D", "Haskell", "Julia", "D"];
  Variant[] dt = variantArray(names, age, language);

  foreach(col; dt){
    foreach(el; col){
      // here I try a kind of dynamic cast operator
      auto x = el.get!(type(el)); // gives error
      write(x);
    }
    write("\n");
  }
}

data_table.d(37): Error: cannot infer type for el
data_table.d(38): Error: undefined identifier 'el'

Help
