Exegesis 4: reduce?

2002-04-03 Thread Andrew Wilson
Hi I'm sure I'm missing something fairly fundamental, but could someone shed more light on the example: # reduce list three-at-a-time $sum_of_powers = reduce { $^partial_sum + $^x ** $^y } 0, @xs_and_ys; specifically what is being iterated over, what gets bound and what does it return? I tho
