A Pascal quicksort screenshot triggers programmer nostalgia

The author posted a screenshot of a classic Pascal quicksort implementation with the caption "i'm this old," prompting a wave of programmer nostalgia. The code is a textbook hand-written quicksort: midpoint pivot, two-way scan and swap, recursive partitioning. The thread's real value is the collective memory of algorithm-contest-era coding, plus a substantive side discussion on how modern sort libraries handle degenerate cases.
