The trick is, again, that the path is often in a variable coming from
user input etc. and you don't (want to) deal with whether it is
relative or absolute. This also still has a slash before relative
paths too.

Another thing is that, while / looks very nice, it makes you have to
use parentheses when you want to directly call a method on the path:

    (somedir / relative_file_path).method()

We have been making examples with
/many/'path'/'objects'/joined_together. But how often do people really
join more than two paths at once?

Sometimes, in interactive sessions, I have wished for this to work:

    somedir(relative_file_path).method()

...which is kind of stupid ;)
