And just to beat the horse a little more, that is equivalent to writing:
class Something
def Something.greet
puts "Hello from #{self]"
end
end
In both cases you call the method on the class object itself (e.g.,
Something.greet).
I'm not sure whether there are subtle differences between those two idioms--it
seems like the self.greet formulation is more common (at least in the rails
world). I think the other one is clearer, personally.
