More documentation for internals, even comments will do.

More low level utilities for constructing complex data structures along
the lines of record-instance. A ways to define high performance analogs
of defstruct's update.

Some control for GC, with more direct support for ref-counted C
structures for example. Or callbacks from native threads. I know about
concurrent-native-callbacks, but it looks too magical to me. Maybe there
are simpler way. It is said that finalizers hurt performance, maybe this
can be improved with hints from C side (for FFI code).

These are random thoughts. I just barely remember about problems I've
had some time ago.
