Note that empty arguments for __VA_ARGS__ aren't allowed by C99, so
clang -pedantic warns about them even in C++20 mode (even though C++20 has
<source>:3:4: warning: must specify at least one argument for '...'
parameter of variadic macro [-Wgnu-zero-variadic-macro-arguments]
clang -pedantic is way too pedantic, if you ask me.
