This means the type checker cannot verify type correctness, but also cannot
construct a contradiction such as zero /= suc

Well, if there actually is an error, your program will be incorrect.
I assume that is reason enough ;-)

generation of correct code, if the code generator does not get
a consistent view of the types of the subexpressions.
