    # File rinda/rinda.rb, line 69
69:     def [](k)
70:       @tuple[k]
71:     end

each( {|k, v| ...}

Iterate through the tuple, yielding the index or key, and the value, thus ensuring arrays are iterated similarly to hashes.

    # File rinda/rinda.rb, line 84
84:     def each # FIXME
85:       if Hash === @tuple
86:         @tuple.each { |k, v| yield(k, v) }
87:       else
88:         @tuple.each_with_index { |v, k| yield(k, v) }
89:       end
90:     end

fetch(k)

Fetches item k from the tuple.

77:       @tuple.fetch(k)
78:     end

size()

The number of elements in the tuple.
