Acknowledgments

My thanks go to Microsoft Research, in particular to James Plamondon, Pierre-Yves Saintoyant, Brad Merrill, Jim Miller, Dan Fay, Erik Meijer, and Don Syme for launching, managing, and supporting this project, for inviting us to participate, and for hosting us in the devlabs.

My sincere thanks go also to my collaborators Thomas Frey, Philipp Kramer, Hanspeter Högger, Karel Skoupy, and Ben Smith-Mannschott for their competent help with the implementation of the compiler, and to Patrick Reali for pointing out an optimization of my previous solution for aggregating definitions.

I highly appreciated the profitable comments by Damien Watkins, Andrew Kennedy, and the reviewers of a previous version of this appendix. Last but not least, I gratefully acknowledge Brian Kirk's vital interest in Active Oberon and his constructive comments.
