Anyone come up with some cool algorithms/templates for D lately?

[janderson]

In the past people have posted these cool algorithms/templates they 
figured out how to do in some neat way with D.  Things like wow, this 
would take INF+ lines in C++ but I can do it in 2 in D.   This seems to 
have died down a bit.   I always found these topics most interesting.

So I'm requesting people to post "cool stuff" they figured out how to do 
in D.
