# go4.org/unsafe/assume-no-moving-gc If your Go package wants to declare that it plays `unsafe` games that only work if the Go runtime's garbage collector is not a moving collector, then add: ```go import _ "go4.org/unsafe/assume-no-moving-gc" ``` Then your program will explode if that's no longer the case. (Users can override the explosion with a scary sounding environment variable.) This also gives us a way to find all the really gross unsafe packages.
