How different users want to respond to errors should not be mandated by 
the library. Therefore it is very good that this library allows you to 
customize it.

There is a difference between protecting against accidental misuse and 
deliberate misuse of a component. Why can rarely protect against the latter.

Having invariants checked only in debug mode is very common, FWIW.
