Only for built-in linear arrays.  Half the point is: What if somebody 
creates a type for which the lower bound is something different?

Thinking about it, maybe we need some symbol like ^ to denote the lower 
bound, and opLowerBound to implement it.  (I've picked ^ along the lines 
of regexps, from which $ is presumably derived.  I *think* this doesn't 
lead to any ambiguity....)
