Hi,

I was watching DConf13 David Simcha's talk recently ... what happened to the idea of creating std.pattern? I do not see it phobos.

I have Singleton design pattern implementation based on David's code: https://github.com/curoles/webos/blob/master/src/d/gem/Singleton.d

usage:
    auto my1 = Singleton!MyClass.get();
    auto my2 = Singleton!MyClass.get();
    assert(my2 is my1);

Thanks,
Igor
