What is the point of keeping start/end? Aren't those baked into 
the array slice? Not storing start end means not having to do 
index arithmetic (minor), reducing struct size (always nice). But 
more importantly, it allows implicit (and conditional) bounds 
checking (awesome), which actually runs regardless anyways.

Or did I miss something?
