I don't. First, I find this more confusing. Secondly, when I once tried 
to implement it, it quickly became a mess to support both noncontiguous 
and contiguous checks. The checks are orthogonal enough to merit two 
separate functions. But then, one can also have different functions 
returning a Boolean.
