  1. The first package specific_name statement creates a namespace and enters it.
  2. Subsequent invocations simply reenter the namespace.
While you may view that as conceptually accurate, that is not really what happens, hence my confusion above. I don't think I've ever come across this being an issue, not least because I would imagine that if you called code on a class you thought had declared, when in fact you had redeclared an existing class, something would break rather loudly.

I can't think of any obvious way to do this within perl, but as you say, it would probably fairly simple just to hack the perl source and recompile.

    The obvious way is to examine all the COP nodes in the compiled program and see that packages don't appear in multiple files. This is test should fit inside of a few lines.

[Corion]: The fun show at $work continues, as The Big Project is now in its second week of frantic live-bugfixing and weekend releases where nobody knows what went live. Nothing has been tested anyway.

Corion watches from the sidelines. Or rather, from behind, as my system only gets output from that process and my programs adhere strictly to the GIGO design principle.
[erix]: ah, that's nice to hear Corion :)
[Corion]: erix: Yeah, the sad thing is that all I can do is document things, so I can point fingers when the auditors come :-/
[Corion]: "I'm here to open tickets and point fingers. And I'm all out of tickets."
[erix]: didn't Sybase have pretty good auditing? :) (this is a vague memory)
[erix]: (culprits often are upstream of db of course)
[Corion]: Ah, how I missed it. After some years, I revisit slashdot on a click-bait link, and it provides the usual humor instantly: "I didn't know Drupal had rules for sex. It must be a plug-in"
