No statistics or math module in core?

[Francois Berenger]

I had to code for my needs:

pearson, spearman (copy-paste from Biocaml this one), mean, median, std_dev
+ some significance test for the Pearson score.

While doing this, I just felt I was wasting my time
(especially once I noticed there is a stat module in Haskell with all of 
this,
crafted by people much more versed than me in numerical algorithms, I 
guess).

And, the cherry at the top of the cake, having to declare pi ...
