The root function returns the current logical root of
the Muq "filesystem". This is equivalent to @$s.root.
Note that this may sometimes to deliberately set to a value
other than the default root, much as a unix process may use
"chroot" to make a subset of the unix filesystem appear to
be the full filesystem.
For consistency with user-relative .x.y style paths,
this function is also available as ..
