Travis-CI Helpers for Perl

I deal with a lot of modules that promise backwards compatibility with older versions of perl, usually back to perl 5.8.1. Since I don't regularly use perl versions that old when developing, accidentally introducing incompatibilities is always a risk. Having a continuous integration system check this for me makes it much easier to catch mistakes like this before they get released into the wild.

Travis CI is a very useful continuous integration service that is free for any public repositories on GitHub. There are issues with using Travis CI for the kind of testing I need though. First, it only provides the last revision of each perl series. Especially in the perl 5.8 and 5.10 series, there are substantial enough differences between them that testing only the latest isn't adequate. Additionally, some of the testing needs to be done on perls built with threading, which isn't included on most of the versions available on Travis. It also is sometimes useful to test without any additional modules pre-installed like Travis does.

Partitions of an Integer

The subject of integer partitions comes up regularly, with multiple threads over the years at PerlMonks, a big chunk of Chapter 5 of Higher-Order Perl, and some pages from Knuth TAOCP volume 4A. Last year I added a partitions function to my ntheory Perl module, for counting integer partitions (OEIS A000041). A few months ago I added a partition iterator (forpart) since I liked the one Pari/GP added last year.

Exporter::Tiny nearing 1.000000

Yes, in my warped mathematics, 0.042 is nearly 1.000000.

Exporter::Tiny is a module I split out of the Type::Tiny distribution. It's an exporter, offering roughly the same capabilities as Sub::Exporter, but with a lighter footprint. I've not massively promoted it, but have been using it in a bunch of my other modules, and other people seem to have picked up on it and started using it too.

The documentation requires a bit of work, but from my perspective the implementation is effectively complete. If you're using it, then I'd appreciate any feedback you have before it's "stable" and thus too late to change.
