The one thing I truely mourn in the changes to the functions is their 
inability to return colour at run-time.

There were certain things that could be done with

#declare fn_pig = function { pigment { ... } }
#declare warped_pig = pigment { function { fn_pig(fn_x,fn_y,fn_z) } }

type constructs in O(n) time which now need O(exp(n)) time and become 
ludicrously slow.

Please note this isn't a complaint or (Heaven forbid!) a feature request 
- just a small requiem for a useful feature fallen by the wayside ...

Bye for now,
