You're both wrong: the limit is FUNC_MAX_ARGS, which hasn't been 8 in
quite some time. It's presently 16 by default, and can be configured
higher at build time.
For the purposes of a frontend application, I think it's best to assume
that the specific limit is unknown --- ie, you should be able to
interoperate with a backend regardless of the FUNC_MAX_ARGS value it
was built with.
