Comment:

 `hash_value` would be nice for iterator range. See [77976] for how an
 example of how to support it, `hash_value` is picked up by ADL.

 The problem with operator bool is really a design flaw in Boost.Hash. It
 should be possible to turn it into an error by defining the macro
 `BOOST_HASH_NO_IMPLICIT_CASTS`, although that isn't defined by default
 because it might break valid code.
