Yes that's the big problem of Yampa: all of the examples are very old, and
some even don't work anymore.
It's the same for the papers/tutorials (they're all 6 years old or more),
and it would be less of a problem if the functions were documented! (Check
hackage, you'll see...)
I find Elerea fine so far, but it is still experimental and more limited
than Yampa.
