Good Kata, always like some recursion to start the day.

Im just curious what the point of having the requirement of one recursive call per character is? My solution halves that and it seems a bit odd refactoring my code to make it be much less efficient. I suppose it makes me think about a different type of solution which is always good!

dcba, like you were reading it right to left

Having the same problem!

Brilliant Kata, learnt alot from this! Would be very appreciative if someone could reccomend me an article/book/resource to learn more about composition and pipelining

Zip isn't working properly...im just getting the input thrown back at me wrapped in another array

Thanks very much for the reccomendation, Im a big fan of this style so will definitely be checking this out

This is so unbelieveably slick, love it and learned alot about what concat can accept!
