This control is like a multi-line-editable-text
control,
except that the value may be any lisp object rather than a string
only. When the control's value is set programmatically to a new
arbitrary lisp object, pprint is called internally on the object to
return a string to be displayed in the control. When the end user
types into the control,
read-from-string is called internally on the
new string to produce a new arbitrary lisp object that is then stored
as the value of the control. Errors are trapped during the reading so
that no break will occur; if an error is signaled during the reading
then nil is stored as the value of the control.
