DI has no place in Ruby. So says Jamis Buck himself:

http://weblog.jamisbuck.org/2007/7/29/net-ssh-revisited

"I've since learned my lesson and have come to understand that
although DI is a nifty technique that works well in some environments,
it is wholly unnecessary in Ruby. Ruby sports an agility that Java
will never know, and can get by without such crutches."
