readln() includes the trailing newline character in the resulting 
string. You can use std.string.strip to remove leading and trailing 
whitespace:

import std.stdio;
import std.conv;
import std.string;
void main()
{
     write("Insert number: ");
     string s = readln();
     auto i = to!int(strip(s));
}
