Is there any very deep magic that says / is the One True Operator
to use for this, given that there's to be an operator for it? For
instance, & has lower correct precedence (so that Path('home') & 'a'*5
does something less unexpected), and doesn't look quite so much
as if it denotes arithmetic, and avoids semantic interference
from the idea that "/" should divide things or make them smaller.
(Though, for what it's worth, I think sticking another subdirectory
onto a path *is* dividing and making smaller: think of a path as
representing a subtree.) You do lose the pun on the Unix path separator,
which is a shame.
