Extensions to the Fold function
This snippet is helpfull in the following cases: 1) After a consolidation operation using the fold function we need to know how many elements have been processed. 2) A consolidation operation needs to use the index of each of the elements processed and we don't want to use the mapi function first. 3) A combination of the above. Since the following snippet just adds a wrapper to the existing Fold function we can repeat the approach for arrays and sequences (including the plinq ones)

Pascal's Triangle (2)
This code sample generates Pascal's triangle as jagged 2D list (list of lists). It takes 0.5 sec to generate 3000 rows (vs 16 sec for http://fssnip.net/23). Tip: try to avoid of using "list1 @ list2" construction.

Pascal's Triangle
Returns the pascal triangle in a 2D list . This snippet computes rows translating the 'visual' method taught at school into Lists and the usage of map2 function. It takes almost 5 seconds to compute 5000 rows.
