Re: Range Expressions

A problem with permitting

      5 to 1 [by +/-1]

implying (5,4,3,2,1), is the use case where you may often write

    1 to count(fred)

to give a set of indices corresponding to each fred, where in the 
absence of any freds you want an empty sequence, rather than the (1,0) 
that would result.
