Hi

It's easy enough to get Integer::Partition working but what if I'm only interested in partitions that have an exact number of summands, like 3? & what if they all have to be distinct?

For partitions of 6, using

my $i = Integer::Partition->new(6);

while (my $p = $i->next) {
  print join( ' ', @$p ), $/;
}

Perl gives me

6
5 1
4 2
4 1 1
3 3
3 2 1
3 1 1 1
2 2 2
2 2 1 1
2 1 1 1 1
1 1 1 1 1 1

But what if I were only interested in the ones with exactly 2 distinct summands, ie

5 1
4 2
... which of course cuts out a lot of possibilities.
