No conflicts...

**Scope Example:**
```d
void main()
{
   import std.stdio;
   {
     enum ver = 1;  // (!)
   }

   enum ver = 208;  // (!)
   double d = ver;

   while (d++ <= ver)
   {
     "Hello!".write(" D Compiler v");
   }

   {
     d /= 100;
     double subVer = 0.1; // (?)
     d.writeln(subVer);
   }

   double subVer = 0.9; // what?
   writeln(d + subVer); // next deneration D3
} /* Prints:
Hello! D Compiler v2.10.1
3
*/
```
