I agree with Jonathan. In addition, instead of the ordinary 
`assert()`, I use the following `assert_eq()`, inspired by Rust. 
This gives me 2 extra usage featıres.

```d
alias equal = assert_eq;
template assert_eq(string msg = "error", R)
{
   enum pred = "a != b";

   bool assert_eq(in R p, in R q)
   {
     static if (imported!"std.range".hasLength!R)
     {
       import std.algorithm : equal;
       if (p.equal!pred(q))
         goto _error_;
     }	
	
     if (p != q)
       _error_:
	
     static if (msg.length) assert(0, msg);
     else return 0;

     return 1;
   }
}
```
