No.  I encountered exactly the instance Integral problem that Dimitry just 
reported.  I spent some time searching for the problem and couldn't figure 
it out.

I could make a lot of half-informed observations on this issue.  I'll 
restrict myself to this one:

It seems like a design flaw that Prelude.hs is mutually dependent 
on several other modules.  My work so far has led me to suspect that 
mutually dependent modules are never necessary.  (And always annoying.)
