Subject:

Does not understand Dumper with no parens

Data::Dumper::Simple needs parens around it's Dumper() function. use strict; use warnings; use Data::Dumper::Simple; print Dumper 42; __END__ Name "main::Dumper" used only once: possible typo at /Users/schwern/tmp/test.plx line 4. print() on unopened filehandle Dumper at /Users/schwern/tmp/test.plx line 4. I don't know if it's worth fixing, but I figured I'd report it.

Try adding a unary plus before the Dump to force disambiguation (+Dumper) Also, check out my Data::Dumper::Names. Unlike ::Simple, it's not a source filter. It's a touch more limited and you have to pass references, but it works well. Cheers, Ovid On Wed Feb 23 19:03:56 2011, MSCHWERN wrote: Show quoted text

I'm not actually using DDS. There's a conflict between perl5i and DDS (actually between source filters and Devel::Declare) and I happened to notice them. Just passing it on. A Devel::Declare/PPI based magic Data::Dumper would be much safer than DDS or DDN, fwiw. On 2011.2.24 4:58 PM, Curtis 'Ovid' Poe via RT wrote: Show quoted text

Data::Dumper::Names only relies on PadWalker for its magic. Do you *really* think this is "much safer" than Devel::Declare? That seems like quite a stretch :)
