Hmm, I wouldn't. The concept of 'exactness' applies to numbers, so I 
would let isexact fail on objects which are not of type Num. But of 
course in Q it's easy for the programmer to then just add an equation 
'isexact _ = false otherwise' to his application if he thinks that this 
is more appropriate.
