c++20 is currently the only viable option, so theres not much reason to put this define under this condition. Also this condition is isolated to exactly c++20 and so its not forward compatible. So it should just be unconditionally added after the c++20 check above.

# ASIO will use std::result_of which was removed in c++20
# force it to use the newer alternative std::invoke_result
myenv.Append(CPPDEFINES=["ASIO_HAS_STD_INVOKE_RESULT"])
