Nishimura and Makoto Matsumoto into D. It is a free function version and  
doesn't use any classes. It also has a template for ranged random numbers.

   eg..
      uint v =  genrand_range!(uint)(1, 10));
      double f =  genrand_range!(double)(-0.5, 0.5))

It can be found at

   http://www.users.bigpond.com/ddparnell/mt.d

To get the object file only, compile with

    dmd -c mt

to get a stand alone self-test version compile with

    dmd -version=main mt

Did you get this from Torus Trooper?  If not then that's highly 
coincidental.

I got it from Makoto's RNG site ...

Hey... I've already implement it in 'helix' on dsource. It is in svn. 
I'll test your implementation on weekend to see which is faster :)

Knock yourself out ;-)  I haven't bothered tuning it, just made it more  
D-like.

Attached is my D port of MT19937. I sent it to Walter last April as a 
proposed replacement for std.random.
