I agree with Thorkil's message to the bug report (although I think the
library name should be libedit or editline - I'm a bit confused about
the relationship of the two).
If a Haskell library or program has a build-depends on readline, then it
should get the same functions everywhere; otherwise dependencies are
meaningless. If a program wants to support both libraries then it can do
Of course, a third library could do the above conditional dependency and
provide an interface to the intersection of readline and editline's
functionalities. Other programs can then use that third library.
