It'd either be so fast it wouldn't matter or the clip would take such a 
small fraction of total evaluation time you wouldn't notice a difference.

You really seem to have no idea how optimization is done...you optimize 
slow parts, not simple parts. The clip() function is likely to take only 
a very tiny amount of total rendering time, and then in only a small 
percentage of scenes. It would be a waste of time to implement it 
internally, the time would be better spent with other optimizations, 
maybe something like allowing inlining of functions, where POV would 
expand a clip() call to the min/max() calls. Or more powerful macros.
