I like the fact that Haskel treats numbers in a generic way, so you can
lift them to any other datatype by instantiating Num.
Can the same be done on other builtin constructs? For example, if I have
[a], can this list be lifted to other types? I guess not, because no
type class exists for the list type?
Does this make sense? I'm still searching for correct terminology...
Thanks,
Peter
