My hours of messing around was a secondary consideration in this case, because I thought loading a module would be slightly less efficient than in-line code, especially for this regularly hit situation (i.e. every page load on my website).

Yes, the code could certainly be inlined, hence the ::Tiny. Although depending on how many items you're generating, a speed boost in generating combinations by a factor of roughly 10x can be achieved with XS modules such as Set::Product::XS.

Don't forget to include me in the credits. My name is spelt: "Some Kiwi Novice @ PerlMonks".

Done :-)
