Does anyone use tuples in Ruby? If so, how may one implement a tuple? Ruby hashes are nice and work almost as well, but I'd really like to see something like the Tuple class in Python, where you can use . notation to find the value for which you are looking. I'm wanting this so that I can create an implementation of D, similar to Dee for Python.
That is _exactly_ what I was looking for. Thanks!

np :) to answer you question though: no i do not use tuples in ruby, as openstructs or otherwise. i use classes at the high end and hashes at the low end :)

A:
Based on the fact that you talk about hashes and . notation I'm going to assume you mean a different kind of tuple than the (1. "a") sort. You're probably looking for the Struct class. eg:
Person = Struct.new(:name, :age)
me = Person.new
me.name = "Guy"
me.age = 30

That's close, but having to name it bugs me. I was looking for something like the (1. "a") sort but with the property get/set notation you describe.

@panesofglass, there's no need to name nothing: a = Struct.new(:name, :age).new; a.name = "Guy"

Can I set `a = Struct.new(:name, :age)` and later say a.new? I would suppose so. I'll have to check that out. It would be a lot more explicit as to what I want.
