- "null" is the proper way to represent the nil value in the diagnostic
format
- hex encoding in diagnostic format was wrong
- struct keys weren't sorted the right deterministic way
It was leaky and required a substantial number of `loc := #caller_location` additions to parts of the core library to make it easier to track down how and where it leaked.
The tests now run fine multi-threaded.
