Some day you may thank for this verbosity, because it encourages
you do program in a purely functional way making your program more
friendly for SMP execution.

Besides Haskell I also write in C++, and there I haven't yet found a
good use for deep subtyping hierarchies. Most of my class hierarchies
consist of a single abstract root and a group of concrete children.
These kind of OO is easily expressible even in Haskell 98.

Then use those scripting languages! I don't want Haskell's semantics
to be "whatever is appropriate in this context".
