I agree with the eight "Without repetition" functions.

But the "With Repetition", I think that providing classes, such as
class gacap::repeat_permutation, is better than functions.  I had not
thought how to privide functions about repetition version.  It's new
thing to me.

I'll read this proposal.  It's a little long for me.
