At one extreme, it is possible to approach the subject on a high mathematical
epsilon-delta level, which generally results in many undergraduate students not
knowing what's going on. At the other extreme, it is possible to wave away all
the subtleties until neither the student nor the teacher knows what's going on.

Engineers
On behalf of the Parrot team, I'm proud to announce Parrot 4.0.0, also known
as Hyperstasis. Parrot (http://parrot.org/) is a virtual machine aimed
at running all dynamic languages.
Parrot 4.0.0 is available on Parrot's FTP site
(ftp://ftp.parrot.org/pub/parrot/releases/stable/4.0.0/), or by following the
download instructions at http://parrot.org/download. For those who would like
to develop on Parrot, or help develop Parrot itself, we recommend using Git to
retrieve the source code to get the latest and best Parrot code.
Parrot 4.0.0 News:
- Core
+ Several cleanups to the interp subsystem API
+ Cleanups and documentation additions for green threads and timers
+ Iterator PMC and family now implement the iterator role
+ A bug in Parrot_ext_try was fixed where it was not popping a
context correctly
- Documentation
+ Docs for all versions of Parrot ever released are now available
at http://parrot.github.com
- Tests
+ Timer PMC tests were converted from PASM to PIR
