If the sequence is supposed to perform an lvalue-to-rvalue conversion, then one will be specified as the first conversion in the sequence. Otherwise, one should not be invented. This should fix clang crashing with "can't implicitly cast lvalue to rvalue with this cast kind", followed by "UNREACHABLE executed at /usr/src/contrib/llvm-project/clang/lib/Sema/Sema.cpp:538!", when building recent versions of Ceph, and the CPAN module SYBER/Date-5.2.0.
