To really convince yourself and everyone else you could compare it
against the spec, for both total and partial values. For our list
library re-implementation we used SmallCheck and a modified version of
SmallCheck for checking partial values. It turned up lots of bugs in our
code and found several instances where the current base implementations
are not the same as the spec (for various good reasons).
