addbb8dd67 fix: redirect 
@cipher1024 I modified your fix. It would produce memory leaks if the
code executed by #eval modifies the stdout.
Here is the problem.
- Your replaces the handler with some new handler `H` and stores the
  old handler `O` in a `flet`.
- Code is executed and replaces the stdout handler with `H'`. The `H`s RC is
  decremented and `H'`s RC is incremeneted. So far, so good.
- Now, the destructor of your `flet` is executed, and it replaces `H'`
  with `O`, but `H'` RC is not decremented.

30a6a2ade8 feat(library/init/data, runtime): remove parray support from runtime, and implement them in Lean using Scala/Clojure Radix trees 
The Scala/Clojure approach for persistent arrays works great with our
`reset/reuse`. We seem to be much more efficient than their
implementations because of `reset/reuse`. The new approach also seems
better than the old one implemented in the runtime, and has a few
advantages:
1- The reroot procedure used in the old approach required
synchronization for multi-threaded code, or we would need to perform
deep copies when sending `parray` objects between threads.
2- We don't need any runtime extension for the new approach.
3- The old approach used "trail lists" for undoing array updates.
This works well for bactracking search use cases, but it is bad
in use cases where we are simultaneously updating the persistent
arrays that have shared nodes.
