Sheesh. I was checking RT bugs and Changelogs, but somehow didn't think about Google :)

Updating Test::Deep solved this. Thanks. (Whew!)

What a painfully long day this is.

    This and some other stuff are the root of my hatred of default exports (and the lack of a nice way to use things without exports at all).

      A bit late reply, sorry, but I find "()" to be quite nice. You just have to cultivate the habit of using it.

        () would be fine if you didn't then have to type

        use Foo::Bar::Woz::Snuts (); Foo::Bar::Woz::Snuts::Wibble($x, $y)

        Python gets it right (well better at least) with

        from import snuts; snuts.wibble(x, y)

        and suchlike. This is pretty much impossible in Perl due to symbol table access being absolute, not relative.

[Corion]: You'll have to look somewhere esoteric for that. Maybe some tied variable or special dualvar can also trigger that. But it's certainly not a common occurrence
[Corion]: And on 5.20, the following also outputs no find:perl -wle 'for my $x ("\x{2000}".."\ x{1fffff}") { if( $x && ! length $x ) { warn qq(<$x>); warn length $x; die } }'
[Corion]: (this time on Unix)
[hippo]: Understood. I'll have to go through the code and see if it's doing anything fancy with ties, dual-vars or non-scalars. In the end, it's probably a bug though.
[Corion]: Aaah - you should be able to do this with overload, but I would hit somebody really hard if they constructed objects that are true but the empty string, and you not knowing about the domain knowledge where this makes sense
