This is now different again, but still [WEIRD].

15​:37 < [Coke]> nom​: 0 but last;
15​:37 <+p6eval> nom ce15be​: OUTPUT«Warning␤»
15​:37 < [Coke]> ... what warning?
15​:37 < [Coke]> ah. no warning. weird.
15​:37 < [Coke]> nom​: last;
15​:37 <+p6eval> nom ce15be​: OUTPUT«Warning␤»

There really is no text after the literal "Warning" message.
