Hi,

i don't understand this little thing:

Suppose, we have "Person" model

class Person < ActiveRecord::Base
end

Why Person.all works ?

Person.all.each { |p| do_something }

This syntax tells us, that we have Person class-object instanciated somewhere ?

Or is it some convention over configuration case ?
