Ok. Let me undersdtand this...

1) I was thinking the <Tield> in the below <animals> function

--------------------------------------------
def animals
       yield "Tiger"
       yield "Giraffe"
end
--------------------------------------------

... calls each of the <animals> blocks below with "Tiger" and "Giraffe"

--------------------------------------------
animals { |x| puts "Hello, #{x}" }
animals { |x| puts "It's #{x.length} characters long!" }
--------------------------------------------


2) But I think from all the explanations I got... below might be true

--------------------------------------------
animals { |x| puts "Hello, #{x}" }
animals { |x| puts "It's #{x.length} characters long!" }
--------------------------------------------

... calls the <animals> function

--------------------------------------------
def animals
       yield "Tiger"
       yield "Giraffe"
end
--------------------------------------------


Does this make any sense ?
