Please vote once and for good: range operations

[Nick Sabalausky]

I'd be ok with any of these:

head/last
head/tail
front/back
current/last
curr/last
car_bonnet/car_boot (just kidding ;))

But beyond that, I'd sooner choose "head/foot" over "head/toe".

If array-style indexing were ever done, I'd be against using negative values 
to indicate distance from end. The semantics of a paramater should never be 
dependant on the paramater's value. (I think that classic book "Writing 
Solid Code" called that a "candy-machine interface", IIRC? Or maybe that as 
something different.)
