variable and save

Alas, Maxima grossly overuses autoquoted functions (fexprs/mspecs) --
and surprisingly fails to use them in a few cases where they make sense
(describe).

You can get around this by writing

    apply('save,[filename,'all])

Since filenames are now normally strings -- which don't need to be
quoted for safety -- perhaps we can change these annoying mspecs to
normal functions.
