    (defvst x (name /: symbol))
    ...load some stuff...
    X

    (cons-a-x)

    ;FOO UNBOUND VARIABLE

The restriction alist in the (SETQ INIFORM  ...) part of the DEFVST macro
has a pair (SYMBOL . FOO) which should be (SYMBOL . 'FOO).  I wrote out
a new source version MC:NILCOM;DEFVST 144 but didn't compile it since I
don't understand all the circular interfile compilation dependencies.
