Some of the D's competitors:

C#
----------------------------------------------------------------------------
using System;
class test{
   public static void Main(string[] args) {
     long a = -5000;
     ulong b = 2;
     long c = a / b; // Operator '/' is ambiguous on operands of 
type 'long' and 'ulong'
   }
}
----------------------------------------------------------------------------
$ mcs div.cs
div.cs(6,14): error CS0019: Operator `/' cannot be applied to 
operands of type `long' and `ulong'
Compilation failed: 1 error(s), 0 warnings


Rust:
----------------------------------------------------------------------------
fn main() {
   let a: i64 = -5000;
   let b: u64 = 2;
   let c: i64 = a / b;
}
----------------------------------------------------------------------------
$ rustc  div.rs

   |                    ^ expected `i64`, found `u64`

   = help: the trait `std::ops::Div<u64>` is not implemented for 
`i64`

Some errors have detailed explanations: E0277, E0308.
