Right on! Thanks Paolo.

Ok.

Yeah usually the names have to be uglified even in the squestered namespace.
So, random_sample -> __random_sample. I believe they all have different 
arguments, so it shouldn't matter if some already are named __random_sample.

Hmm. This is to be avoided if at all possible.

Thanks again for all your hard work!
