`argparse`, `read`, `set`, `status`, `test` and `[` now can't be used as function names anymore. This is because (except for `test` and `[`) there is no way to wrap these properly, so any function called that will be broken anyway. For `test` (and `[`), there is nothing that can be added and there have been confused users who created a function that then broke everything. Fixes #3000.
