Ahhh.. 'our' is something I've never seen mentioned anywhere; nothing in the Camel book index, nor in the Llama book index on it... but how handy that's going to be :)

Making the 'library' into a 'module' is the next step. I don't necessarily want to distribute it but it's probably (the proverbial) 'GoodThing(tm)' to implement these functions via a module, rather than a library; I've not built a module yet so I still have to study-up on that side of things, particularly as regards the exporting of data, subs, etc.

Many thanks for the helpful suggestions though.
