I don't think an additional switch helps; a depth parameter is the right
way to specify the depth. I also don't think it's a configuration parameter as
it is specific to the method call.
What I'm suggesting is to simply not have so many overloads. A method like
`fileStream` need only add the depth parameter to one of its overloads, not
all. It can go on the overload with the most arguments.
