Categorizing Ranges

[Mike Parker via Digitalmars-d]

I'm looking for ideas on how to label the ranges returned from 
take and drop. Some examples of what I think are appropriate 
categories for other types of ranges:

Generative - iota, recurrence, sequence
Compositional - chain, roundRobin, transposed
Iterative - retro, stride, lockstep
XXX - take, drop

What to put into the XXX? I first thought of "Greedy", but that 
has an association with "greedy algorithms" that I don't really 
like. That led to "Selfish", but it's admittedly not that 
appropriate. Beyond that, I'm stuck. Any and all ideas 
appreciated.
