An idea for numpy/__init__.py:

if sys.version_info[:2] >= (3, 7):
    __all__ += ['__don_t_do_this']

    def __getattr__(attr):
        if attr == '__don_t_do_this':
            warning.warn("Don't do this')
            return None
        raise AttributeError

But why?

Until python itself starts to do this, I don't think we should enforce this.

Agreed. This will breaks a huge amount of code, just to teach better habits. That's what docs are for. I suggest to close this.

Nice trick by the way:)

It was not the most serious suggestion to be begin with. But the trick may be useful if we deprecate other attributes. Since we can modify the deprecation warning in the case of * imports to not be a difficult to understand spam (especially difficult to understand when it comes to avoiding the warning).

Closing this, it wasn't very serious about actually deprecating from numpy import *, and I think we are now comfortable enough with __getattr__ to not have an issue as a hint.

If we deprecate a name, it is also removed from __all__.
