Your definition of a design pattern is more precise than mine for sure. In FP its not "an abstracted, re-usable piece of functionality" unless it can be made in

Your definition of a design pattern is more precise than mine for sure. In FP its not "an abstracted, re-usable piece of functionality" unless it can be made into a library, as far as I know. But it seems to me that FP forces you to look at programming in terms of what you are doing to transform data. In that case I can't see why having enough libraries won't do the job.
