For instance, I have a list (1 2 3 4 5 6 7 8 9 10 11), and want to roughen it by 3 elements (or another length) to get ((1 2 3) (4 5 6) (7 8 9) (10 11)). What pretty code could I use for this? Thanks.

When would you NOT want to use functional programming? What is it not so good at? I am more looking for disadvantages of the paradigm as a whole, not things like "not widely used", or "no good debugger available". Those answers may be correct as of now, but they deal with FP being a new concept (an… >>> More

It seems to me that functional programming is a great thing. It eliminates state and makes it much easier to automatically make code run in parallel.
