There is also the xml package from Galois:

Why?
because you may write in other module

if class A includes functions, it may be problematic to determine

Instance instantiation is *not* search, and *not* similar to
subclassing in OO languages.
Both your instance declarations simply add constraints to functions that use it.
Here's a more concrete example:

Hi folks:
I'm trying to use hackage/cabal/cabal-install, and I have a feature
request: it would be nice if the metadata about the package, which is
displayed on e.g. hackage-scripts/package/HTTP had a field for the
revision control tool that is used on that package (if any) and the
Haskell programs with particular constraints (i.e. pure, total Haskell, doesn't
primarily call gtk...)
Yup, and that's a great thing that we should be evangelizing to
all potential users. No need to go overboard and tell them that
there will never be a crash, though.. The robustness claim is
I'd like to be able to write something like
map zipWith ([1,2,3] = printMyInferredType)
and have the compiler treat 'printMyInferredType' as undefined, but
also produce the side effect of printing out its inferred type.
What's the easiest way to simulate this with what we have now?
