It doesn't matter if the functions are non-standard. If the values are
treated differently by any function except eq? and functions derived
from eq?, they must definitely not be eqv?.
In case of doubt it is always safe to decide that certain values are
not eqv?, as long as each value is still eqv? to itself.
