# TODO: portability-avoid-pragma-once: should be fixed eventually
# bugprone-use-after-move (hicpp-invalid-access-moved is its alias) still flags
# the basic_json move constructor, which forwards the whole object to its base
# class (#5724), and two forwards in the error-message construction of
# at(KeyType&&) (json.hpp, both overloads: find(std::forward<KeyType>(key))
# followed by string_t(std::forward<KeyType>(key)) in the throw), which #5689
# rewrites. Re-enable both checks once those changes have landed.
# portability-avoid-pragma-once: kept disabled on purpose. #pragma once is accepted
# by every supported compiler, and tools/amalgamate/amalgamate.py strips it from
# single_include, so there is nothing left to fix here.
