// used as a shared library. Otherwise, lib's state won't be shared among
// different user programs and user libraries. However, this library can be
// safely compiled and used as a static or header-only library only when it is
// being used by a single program unit (e.g., a single program with only
// statically linked libraries that check contracts).
