This means that we need to change the DFG abstract heap hierarchy to have a notion of Heap that subsumes all that World previously subsumed, and a new notion of Stack that is a subtype of World and a sibling of Heap. 1072118 1 247339 fpizlo 2015-02-25 13:40:53 -0800 Created attachment 247339 the patch 1072125 2 247339 ggaren 2015-02-25 13:45:47 -0800 Comment on attachment 247339 the patch r=me
