My apologies, I forgot this ticket completely.  I should have wrapped up this discussion.

 We are planning to add the following features of the random sampling to Array.
 
 1. Weighted random sampling.
 2. Sampling with replacement.
 3. Iteration.
 
 It is discussed in ruby-dev (Feature #3647 and #4147).
 
 
 API will be:
 
 Array#sample([size, [opt]])
   - Random selection without replacement.
   - Returns a new array when size is specified.
   - opt:
       weight: proc or array
       random: Random instance
 
 Array#choice([size, [opt]])
   - Random selection with replacement.
   - Returns a new array when size is specified.
   - opt: same as above.
 
 Array#each_sample([opt])
   - Random selection iterator without replacement.
   - Choose a random element and yield it.
   - Returns an Enumerator if a block is not given.
   - opt: same as above.
 
 Array#each_choice([opt])
   - Random selection iterator with replacement.
   - Choose a random element and yield it.
   - Returns an Enumerator if a block is not given.
   - opt: same as above.
