Another interesting(?) behavior, when run from a non-existing (deleted) working
directory:
weakly_canonical("foo") returns "foo", while weakly_canonical("./foo") throws:
> terminate called after throwing an instance of

> what(): filesystem error: cannot make canonical path: No such file or
> directory [.]
