Comment (by kirsten):
enumFromThenTo looks like a good producer to me (it's defined in terms of
map, or at least the default implementation is, just like the default
implementations of enumFrom, enumFromThen, and enumFromTo). Can you be
more specific about what problem you're seeing? If you have code using it
that you would expect to be deforested that isn't, could you post a test
case?
