It seems like it would good to have: 
package non_main;

[download]
check the symbol table and warn if the non_main namespace exists. I mean that such a warning could be optionally turned on.

I will probably add a lint process to catch the ordinary package statements and that should serve me well enough.

But I am curious

Be well,
