Thanks for all the comments, everyone. I’m busy preparing for a holiday and then will be on holiday (obviously…) so don’t quite have time to respond to everyone, but keep the discussion going and I’m hoping to collate things into a summary document elsewhere when I get back.
Always nice when people actually explain cryptics - I think too many people still see it as a bit of a “Well I’m cleverer than thee” thing, when there’s actually a fair bit of structure and looking-stuff-up to it really. (A bit like coding, I guess…)
