The user can supply FAST or UNDOABLE versions of ACCESSFNS forms
in the following manner. An ACCESSFNS record looks like
(ACCESSFNS record.name ((field.name fetchdef replacedef) ...]
As before, "fetchdef" and "replacedef" can be either a function
name, a lambda expression, or a form in terms of the variables
DATUM (and NEWVALUE).
In addition, they can be property lists with the properties
FAST/UNDOABLE or STANDARD, e.g.
(DEF (STANDARD GETD FAST FGETD) (STANDARD PUTD UNDOABLE /PUTD]
forms in terms of DATUM/NEWVALUE and function names may be freely
mixed in the property list.
