then verified in tests.

/*
* A factory macro for defining the assertions and expectations for the basic
* comparisons defined for the built in types.
*
* Unfortunately, there is no common type that all types can be promoted to for
* which all the binary operators behave the same way as for the actual types
* (for example, there is no type that long long and unsigned long long can
* both be cast to where the comparison result is preserved for all values). So
* the best we can do is do the comparison in the original types and then coerce
* everything to long long for printing; this way, the comparison behaves
* correctly and the printed out value usually makes sense without
* interpretation, but can always be interpreted to figure out the actual
* value.
