Why does this overflow? (a try at the sieve of Eratosthenes)

I tried implementing the sieve of Eratosthenes in Clojure. The approach is to loop while (A) keeping my current list of numbers which have not yet been eliminated, and (B) keeping track of the number I'm "on" (checking for multiples thereof). Here's what I came up with (in a foo.clj file): ~~~

algorithm help: extracting groups of consecutive ints from a sorted list

If you've got a sorted list of numbers, for example: [1 3 4 5 7 9 10 13] where some are consecutive, how can you pull out the consecutive runs? That is, either produce [1 [3 4 5] 7 [9 10] 13]; or maybe something like [[1 7 13] [3 4 5] [9 10]] ; (the first vec is the elements le
