I believe this used to work:
(ps-to-string 'some-symbol)
Now it doesn't:
No methods applicable for generic function #<STANDARD-GENERIC-FUNCTION PARENSCRIPT::COMPILE-PARENSCRIPT-FORM> with args (NIL SOME-SYMBOL) of classes (NULL SYMBOL) [Condition of type PROGRAM-ERROR]
... apparently because of the lack of an implicitly expected compilation environment.
