=begin
 Array#sample does not support sampling with replacement directly, so we 
must write codes like the following to obtain samples with replacement.

   samples_with_replacement = n.times.map { source.sample }

 If Array#sample has the argument for switching with/without 
replacement, we can write it as follow.

   samples_with_replacement = source.sample(n, true)

 The patch was attached.  Please consider to merge.
