I've just moved pdd22 out of the clip directory, marking it as ready for
beginning implementation efforts. Comments on the pdd are welcomed. A
few things worth highlighting:
- I/O layers will be replaced with role composition.
- Parrot's concurrency model for async I/O is a modified form of the
callback function model, combined with a central concurrency scheduler
(see recent comments added to PDD 25).
- One question still under discussion is error handling. Should all
errors be exceptions? Integer status codes? More details in the PDD.
