Feature #3647: Array#sample(n, replace=false)

=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.
=end
