For your information: > - Should the procedure be nullary or n-ary? (MzScheme's VOID > procedure is n-ary and ignores all of it's arguments. Chez's and > Gambit-C's VOID and Scheme 48's UNSPECIFIC are nullary.) Bigloo uses a nullary function. > - Should there be a literal? Bigloo has one and I think that it is convenient. People uses it from time to time. -- Manuel
