+// todo:
+// - [ ] loom migration
+// - [ ] helpers to convert c3_w to c3_d
+// - [ ] expand page size?
+// - [ ] modify free lists length?
+// - [ ] new type for mugs (c3_l -> ?)
+// - [ ] modules: allocate, retrieve, vortex, imprison, noun types
+//
+// approach:
+// - huge change
+// - small, incremental updates
+// - widen pointers first, fill rest with zeroes
+// - start using them
+// - rather, rinse, repeat
