Unfortunately __VA_OPT__ forces you to C20 / C++20, so that would likely be a no-go. One option would be to add a macro that introduces a unique name into scope for you, like...

#define DOCTEST_TO_STRING0(x) #x
#define DOCTEST_TO_STRING(x) DOCTEST_TO_STRING0(x)

#ifdef __COUNTER__
  #define DOCTEST_UNIQUE_NAME() DOCTEST_TO_STRING(__COUNTER__)
#else
  #define DOCTEST_UNIQUE_NAME() DOCTEST_TO_STRING(__LINE__)
#endif /* __COUNTER__ */
#define UNIQUE_NAME DOCTEST_UNIQUE_NAME

...with its usage being along the lines of...

SCENARIO(UNIQUE_NAME()) { /* Hacking... */ }
SCENARIO(UNIQUE_NAME() * doctest::may_fail) /* Hacking, but it might be a bit flaky for now... */ }

from doctest.
