Found and fixed. The BNF action rule for "head SUBLIST rhs" used the monify function, which was completely unnecessary (I think this was a cut-and-paste from elsewhere and I didn't remove the monify). The new sweet-expression implementation now passes the sweet-expression test suite, and processes both sweeten.sscm and a version of letterfall correctly. (Or at least, it produces the same results as the old one did.) --- David A.
