I'd find it more consistent if string returned what is currently [string(x) for x in 0:2]. And it seems to me the latter operation is much more common than expecting "[0,1,2]", which is useful only in very special contexts. Maybe call it deparse, stringrep or something like that? Or simply use the String constructor, which by definition must return a String object, not an Array{<:String}?

This is related to #1470.
