Subject: getting a n-th key-value pair from a hash

Hi!

suppose I have this hash:

data = { "a" => 1, "b" => 2, "c" => 3 }

I'd like to get a random pair from the hash.

so

data.get_pair(data.rand)

should return ["b", 2] for example.

How could this be done? I cannot find any method in the documentation.

Thank You!

david
