[sigh] I feel the debate should be more about where to put things we 
have already worked hard to create. rather than to eliminate them to 
make a release. If you intend to implement Riddlers later after release 
rather than before, it would be wise to keep sign around.

My time and efforts are focused into the features I want to see 
available in the statistics library (and the features I *enjoy* working 
on), others do the same and the library grows in functionality. Be very 
carefull about taking away the things that other developers on the 
project are working with great interest on.

All I can say as a developer on this project is, I use them, I enjoy 
working on them, (they are moments as natural as mean and variance and 
they natural incusions into descriptive statistics). I've worked hard on 
their development, and I'd really like them to stay part of the package.
