Just because it _can_ be done, dosen't mean it should be. Consider the
innocuous table
Range[N[1/3, 16], N[9/3, 16], N[1/6, 16]]
Naively, we might expect this to return
Range[1/3, 9/3, 1/6]
but it dosen't, at least not under 5.0.1 Windows. Still, side effects like
these are relatively easy to spot, and hopefully, real-valued iterators
required by the OP fall into this category.

Dave.
