Fixed on autodie reference, I was using it before 5.10 and that was my oversight. Glad to know it is in core now, and has been for a while!

As, for utf8, I wholly disagree, the encoding of the perl source and of the IO stream should be separate. You can argue that both should be UTF8: but, I don't think you can logically argue that the Perl source shouldn't be utf8. Even if you're not using UTF8, and even if the files you want to read aren't using utf8, the authors using nextgen and contributing to CPAN should be encoding their perl source in UTF8. We shouldn't assume they have the same legacy-needs you do.

    That's not at all what I'm arguing.

    I simply made the experience that concatenating binary strings and decoded strings lead to nasty errors. So if you don't bother to decode strings on input, telling Perl that the source file is UTF-8 is harmful.

    If your script or module is written in UTF-8, input and output data is UTF-8, but you don't decode or encode, everything "works" in the sense that the output is correct UTF-8 (though of course the strings don't follow proper Unicode semantics internally). In this case use utf8; leads to incorrect output.
