Hm, it's not at
http://wiki.rubygarden.org/Ruby/page/show/ExampleDesignPatt...

Anyway, it looks to me like some combination of .clone plus a factory.
I'm not sure there's any real savings in Ruby to doing things this way,
but I'd be happy to be proved wrong.

Why no go the extra step?

DB = Prototype.new{
host 'localhost'
port 4242

connect does{ 'do something' }

inspect does{ [host, port].join ':' }
}

Why not even this:

connect { 'do something' }

inspect { [host, port].join ':' }
