As a worked case I'll point to CZMQ, which is absolutely stuffed with
asserts. Yet it's very reliable. In fact there's no contradiction
here. You misuse the contract, it kills you. Thus, CZMQ apps are
trained to behave better.

Perhaps for language bindings, returning EINVAL is an option when
passing garbage arguments. Yet I'll repeat my assertion that if an
application or binding is incompetent enough to pass garbage
arguments, then it cannot be competent enough to check errors
