Obviously, he is demand as a speaker now, so he has been working on his english. And most listeners are willing to listen, because he knows what he is doing.
It's questionable whether Rails should be rewritten to simply use variables instantiated by named params instead of internally deciphering them from an options hash
I'm not in posession of 2.0, so I some of this is speculative, hope it helps though :-)
The Hash object at the bottom of the arguments list Matz was explaining about, can actually have the brackets omitted, but is still interpreted as :a => hash. When you want to pass another hash in the parameter, you have to explicitly wrap them both in brackets, or instantiate by Hash#new
If you have a function
def google(opts) puts opts[:foo] + boo end
This is how it looks
google {:boo => "foo"}, {:far => "bar"}
