I should have expected that answer, but couldn't believe that you think
it's a good idea to implement that obese filesystem path API for URLs ;-)

Shouldn't we instead have:

 a) .open()-able objects blessed in the stdlib & stdlib docs, as a
separate interface from the path interface (I guess that would be an
argument in favour of path implementing that one-method interface, as long
as it's not tied too tightly to the fat path interface)

 b) a path object with a thinner interface (I know you've already
expressed that preference yourself...)?
