You can have a fast path for arrays and fall back to the slower, 
more generic version for other ranges.

But yes, the whole point of ranges is to decouple your algorithm 
from the source of the data it operates on. If you *want* your 
algorithm to be coupled to a particular source of data, then 
ranges will only get in your way. (Although it may be worth 
asking yourself: are you really sure that's what you want?)
