Well, people are expected to consider the possibility files are named "0", or that files can end with "\n0" (for the latter, there are even warnings build in in Perl).

I'd say that if you code general solutions, and that's what the OP was doing, you should consider such possibilities. Programs that run in a specific, or controlled environment may not have to take such things into consideration.

Oh, and don't get the idea that a package of '0' has never happened. The original post triggered a memory. Years ago, a co-worker was working on some complicated template system. Some code also dealt with 'ref' and blessed objects. And code *did* fail because some other code (which generated code) blessed objects in the package '0'.

OTOH, I've never encountered a supposedly text file that ended with "\n0". That doesn't mean I won't check for definedness when necessary.

Secondly, shouldn't bless [], 0; be considered a bug and reported for fixing?

Uhm, why? Just because it's inconvenient? Then we might as well forbid filenames to contain spaces and Microsoft Outlook - that's inconvenient as well. ;-)
