Dear bearophile, without the table() function in the standard 
library, this code does not work.

After hours, I managed to write code to generate random strings 
based on your code.

```d
import std.array : array;
import std.ascii : letters, digits;
import std.random : choice, Random, unpredictableSeed;
import std.range : generate, take;
import std.stdio : writeln;

auto rnd = Random(unpredictableSeed);
auto symbols = array(letters ~ digits);

generate!({ return symbols.choice(rnd); }).take(10).writeln;

```
