Changing in the middle isn't what I want to do.  I want to change first
thing, but have the change, which was specified in a particular (startup)
file, persist after we're done reading that file, into the REPL and into
(non-library) files loaded from the REPL.

Of course if you make Non-Cartesian the default then you don't have to
humor me in this.  :-)

I agree that one should /also/ be able to do the file-attribute thing
that you want.
