List::Permutor::Repeat - Process all possible repeat permutations of a list
组合数学，可重复排列
use List::Permutor::Repeat; my $perm = new List::Permutor::Repeat qw/ a b /; while (my @set = $perm->next) { print @set, "\n"; } #aa #ab #ba #bb
This is repeat permutation.
Not repeat elem permutation see Tom Phoenix's List::Permutor.
初始化，传入一个数组
Returns a permutor for the given items.
取出下一个可重复的排列
Returns a list of the items in the next permutation.
for example, the repeat permutations of (1..5) first: (1, 1, 1, 1, 1) last: (5, 5, 5, 5, 5)
取回当前的排列
Returns the list of items which would be returned by next()
重置排列，从头开始
Resets the iterator to the start.
