[Haskell-cafe] pi

Jonathan Cast adds 'something' to a discussion about pi. 

I commented the statement of Yitzchak Gale, who answered some point
of Dan Piponi: 

>> > A default implementation of pi would only increase usability,
>> > not decrease it.

I said: 

>> Can you provide some examples of this "increased usability"?  
>> 
>> If possible, with a *relevant* context, which shows that PI should belong
>> by default to the class Floating (whatever we mean by that...) 
> 
> pi /is/ a method of class Floating.  It just doesn't have a default
> implementation.

Now, do you have anything to propose, or you just want to criticise
my wording? If I ask why should I be a nice fellow, and you say that I am
a nice fellow, this makes me happy, but doesn't answer my question... 

Mind you, we are discussing possible solutions, not just the status quo.
