each is actually a method name that's used for many of the container types; arrays use it too: 

arr.each { | x |  # iterates the elements, NOT the index 
  puts x
}

Basically, each here is just a method that recieves a block (like perl's anonymous subroutines) as an argument. The container type is then responsible for calling the block for each element.

Any class can provide it's own each method - this is not a built-in function like perl's foreach.
