Now that's interesting. Your post inspired me to dig a little deeper... it looks like the autovivification is still happening, but not on the lexical %stopper. Instead the global %::stopper is affected. Which makes sense, I suppose, because %::stopper is what was being affected in Abigail's original snippet, and with no lexical on scope, %stopper (i.e. the symbolic reference) was really referring to %::stopper. Very interesting, I certainly learned something. Thanks for pointing that out!

use Data::Dumper; my %stopper; $x = 'stopper'; exists $x->{'y'}->{'z'}; print Dumper $x; print Dumper \%stopper; print Dumper \%::stopper;

XML::Simpler does not require XML::Parser or a SAX parser. It does require File::Slurp.

[Corion]: Oh yay. I wonder why a very simple change in a program doesn't elicit a diff, and now I see that my diff program seems to have a bug ;)
[1nickt]: marto thanks for asking, so far so good. A pretty modern stack and decent procedures, although rather too much home-built stuff (e.g. a logging role that should tries to duplicate Log::Any).
[Corion]: No. It's just that I'm comparing the same output file twice, instead of comparing the output files of the two runs %-)
