Hello everyone,
I am developing a toolset in which I have several (multiparameter)

It is often the case that I can only define a data-type X as an
instance of one such class (say A), if X is an instance of another
class (say B);
The thing is that, while it is hard for

No, it's the other way round. Every HUMAN is also a BEING, hence
HUMAN(t) = BEING(t)

Perhaps Haddock could exclude class instance reporting when it cannot find a

The cannot find documentable link problem also comes up
in situations like this (that don't involve type classes):

well, expect that you cannot use the type's name in signatures,
so you'd have to rely on type inference.

i believe that a valid idiom is to define a class C that has no functions,
but requires any instance to also be of type classes A and B, so that you
can write: C a = blah
rather than (A a,B a)= blah, though I don't know how often such is used in
practice
the same idea should apply more

Hi all,
I've been considering using Haskell for my natural language processing
project. Due to its nature, it has much to do with Unicode.
Unfortunately, Haskell escapes UTF8 characters. I've been able to
output these strings via System.IO.UTF8.putStrLn (though I wish it was
less painful), but
