You're not the only one that's confused by the way the operator specifications
are split between the language book and the F+O book, but there is some method
in the madness: in general operators are polymorphic, and the language book
describes the logic that decides which of the various (non-polymorphic)
functions needs to be despatched. In this case there is no suitable function to
handle non-node-operands, so a type error is raised during the despatch process,
not by the function itself.
