In The Implementation of Functional Programming Languages by S.P. Jones,  
section 2.5.3, page 32 it is written:
Eval [[*]] a b = a x b
Eval [[*]] _|_ b = _|_
Eval [[*]] a _|_ = _|_
but in section 2.5.2 it is said that _|_ is an element of the value  
domain.
What business does it have on the left side of the '=' ?
Can you help me send him to his room ?
