In recent versions of the GHC libraries, constrFields (as defined here
http://www.cs.vu.nl/boilerplate/library/Data.Generics.Basics.html) has
disappeared. I failed to figure out another way to get the names of all
fields of a constructor.
Have I overlooked anything? Do I have to use Template
The problem is that constrFields is not included with 6.2.1.
You would need to build GHC from CVS.
It will be in 6.4 for sure.
And yes, you are right, there is no other way to get the names
of all fields of a constructor.
