This bug comes up quite often for me.

Example test input:-

   this log:forAll :x, :y, :z .
   [ :blargh ("y" "z") ] .
   { :x :blargh :y } log:implies { :y :blarghOf :z } .

The error raised:-

            Traceback (most recent call last):
  File "/home/2000/10/swap/cwm.py", line 615, in ?
    doCommand()
  File "/home/2000/10/swap/cwm.py", line 607, in doCommand
    _store.dumpNested(workingContext, _outSink)
  File "/home/2000/10/swap/llyn.py", line 1549, in dumpNested
    self.dumpFormulaContents(context, sink, sorting=1)
  File "/home/2000/10/swap/llyn.py", line 1570, in dumpFormulaContents
    self._dumpSubject(currentSubject, context, sink, sorting, statements)
  File "/home/2000/10/swap/llyn.py", line 1638, in _dumpSubject
    self.dumpStatement(sink, s.quad, sorting)
  File "/home/2000/10/swap/llyn.py", line 1680, in dumpStatement
    self.dumpStatement(sink, t.quad, sorting)
  File "/home/2000/10/swap/llyn.py", line 1701, in dumpStatement
    self._outputStatement(sink, triple)
  File "/home/2000/10/swap/llyn.py", line 1387, in _outputStatement
    sink.makeStatement(self.extern(triple))
  File "/home/2000/10/swap/notation3.py", line 922, in makeStatement
    raise RuntimeError ("Should only see first and rest in list mode",
triple)
RuntimeError: ('Should only see first and rest in list mode', ((1,

DanC has come across this error before, last September, but it was for a
different test case:-

http://ilrt.org/discovery/chatlogs/rdfig/2001-09-19.html#T21-08-30

and one which, I might add, now works:-

$ cwm --rdf http://www.daml.org/2001/03/daml+oil --n3 | wc
    401    1419   13296

Cheers,
