Beside the current ones, I'd like another pseudo-random number generator to be present in the std.random module, the R250/521: http://en.literateprograms.org/R250/521_%28C%29 http://en.literateprograms.org/Special:Downloadcode/R250/521_%28C%29 The implementation is easy, the quality of the generated numbers is not bad (worse than Mersenne Twister but better than congruential generators), and the performance is very good (among the best, in my tests). So it has a high performance for its quality level. I suggest to use the Mersenne Twister to initialize its r250_buffer and r521_buffer arrays. I have a D translation, if you want.

Are you still interested in adding this generator? If so, would you mind putting in a pull request on github?
