Reserve some builtin names

Browse Source 
`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.
