Hey huck, If you're recommending that switch, could you please show us an example of it in use (ie. what happens when it's used), and let us know the purpose of using that var?	[reply]

http://search.cpan.org/~smueller/Data-Dumper-2.154/Dumper.pm#Configuration_Variables_or_Methods Style 0 spews output without any newlines, indentation, or spaces between list items. It is the most compact format possible that can still be called valid perl.	[reply]

Right, but it's just nice when commenting that one provides an example within their reply, so it's easy to see, and one doesn't need to travel off the page unless they need to further their understanding of the documentation. Also, it doesn't 'quite' print it out in as compact format possible to be considered Perl... there's still some whitespace/characters that can be eliminated so the Golfers can remain happy ;) `perl -wMstrict -MData::Dumper -E '$Data::Dumper::Indent=0; print Dumpe +r {a=>1, b=>2};' $VAR1 = {'a' => 1,'b' => 2};` [download]	[reply] [d/l]
