+  * test: times.format with the FFI
+- GC: variation of m&s GC
+- GC: implement simple generational GC
+  * first version: mark black in write barrier
+  * second version: introduce fake roots instead of marking black
+  * third version: find some clever heuristic which is preferable
 - acyclic vs prunable; introduce GC hints
 - implement constructors + full 'not nil' checking
