    each_pair {|(name, value)| ... } -> self
    each_pair -> enumerator

Calls the given block with each member name/value pair; returns `self`:

    Customer = Struct.new(:name, :address, :zip) # => Customer
    joe = Customer.new("Joe Smith", "123 Maple, Anytown NC", 12345)
    joe.each_pair {|(name, value)| p "#{name} => #{value}" }

Output:

    "name => Joe Smith"
    "address => 123 Maple, Anytown NC"
    "zip => 12345"

Returns an Enumerator if no block is given.
