lol. I misinterpreted "top level" directory. I thought you meant "/" and
were observing that I "cd .." before checking if I'm in "/" (which I
also potentially do, thus my note about the Null Object Pattern).

But when you said "top level" you meant what I've called "base".

And, yes, that is quite deliberate. You have said "Nice!" sarcastically,
but it's actually "Nice!" for realz.

If you're in the base directory of a sub project, my solution will move
you to the parent project base, if there is one. If there isn't one, it
will leave you where you are. This is the best functionality in my view.
Why have multiple calls to base() leave you in a sub project, the base
of which you are already in?

May the Force be with you,
