[issue29446] Improve tkinter 'import *' situation

[Terry J. Reedy]

Terry J. Reedy added the comment:

This issue is spun-off from #29162, which was about idlelib.pyshell depending on import * importing sys.

'wantobjects' does not have the same bug potential as stdlib imports.  But, Serhiy, if you care about it or otherwise prefer __all__,

__all__ = [name for name in globals() if not name.startswith('_') and name not in {'enum', 're', 'sys', 'wantobjects'}]

should work if placed near the end of the file, just before 'def _test'.  Except for the exclusion set, I presume that 'import *' does essentially the same iteration
