Henrik,

Thanks. I tried

ghc --make Main.hs on the code from 
http://www.cs.hmc.edu/courses/2006/spring/cs182-3/afrp but got

Compiling ObjectBehavior   ( ./ObjectBehavior.hs, ./ObjectBehavior.o )

./ObjectBehavior.hs:37:56: parse error on input `->'

The code in examples/SpaceInvaders for ObjectBehavior.as is identical so 
  I assume that won't compile either. Why .as?

If anyone has got this working please let me know.

I tried making www.haskell.org/yampa but got

[dom at tility afrp-0.4]$ make
make -C src
make[1]: Entering directory `/home/dom/yampa/nilsson/afrp-0.4/src'
ghc -c  -fglasgow-exts -O -package lang -package concurrent   -o 
AFRPUtilities.o AFRPUtilities.hs

AFRPUtilities.hs:169:46:
     Ambiguous occurrence `>>^'
     It could refer to either `AFRPUtilities.>>^', defined at 
AFRPUtilities.hs:106:2
                           or `Control.Arrow.>>^', imported from AFRP at 
AFRPUtilities.hs:90:0-10

So it looks like the code has rotted a bit. I'm assuming the code from 
hmc is in better shape (as it seems to be in a Spring '06 directory and 
the compilation got a few modules further) and may have a go at seeing 
if I can get it to compile.

Dominic.
