[Haskell] Liber Amicorum for Doaitse Swierstra.

[Jurriaan Hage]

Dear all,

Prof. Doaitse Swierstra is retiring on August 1 of this year, and is
leaving the very functional programming minded Software Technology
group that he has led for many decades.

We have compiled a Liber Amicorum in his honour that we handed
to him after his farewell speech on May 30th. You can find a download
of this book at:

Not all contributions are ``technical'', and not all of them are in English, but
counting up the pages, I guess about 75 percent is.

best,
Jurriaan Hage
