I thought about adding functions, possibly random, very probably abs & 
some hash, but I felt it would be more for a second round.

The other point is that although uniform random is fine, the gaussian and 
exponential ones require an additional floating point argument which means 
handling some typing.

The current patch is "just" about handling operators as before, although 
in a much nicer and extensible way, thus I would suggest to let Robert's 
patch more or less as it is, and people will be able to propose new 
extensions later on.
