To be honest I shy away from anything that relies on Filter::*.

I don't see it as particularly necessary here either, as to me, the greatest annoyance has always seemed to be the fact that named variable output requires passing two parallel arrays — rather than, as would seem more natural, hash-like named parameters. Something like this would suffice for me:

warn Data::Dumper->Dump( foo => $foo, this => \%this, array => \@array, that => \%that, );

This also makes the subtle typo you demonstrated much less likely.

(Assume that you are allowed to say '$foo' => $foo where you need the control.)

I am guessing this is all because whoever wrote Data::Dumper wanted the Dump() function to more-or-less DWIM, so that you wouldn't have to remember to call different functions for named or anonymous output. That could easily be achieved as well — Dump() could expect exactly one array- or hash-ref for anonymous or named output, respectively. This gives

warn Dump { foo => $foo, this => \%this, array => \@array, that => \%that, }; #vs warn Dump [ $foo, \%this, \@array, \%that ];

The price is, of course, that you have to use the appropriate set of delimiters.

Another thing that bugs me about Data::Dumper is the OO interface. The constructor takes no options, you have to set them all with one mutator call each. I'd much prefer the former:

my $dumper = Data::Dumper->new( purity => 1, terse => 1, deepcopy => 1 + ); warn $dumper->Dump( [ $foo, \%this, \@array, \%that ] );

Or something along these lines. There are numerous problems with my propositions here; I've never entirely thought this all through. All I'm really saying is that Data::Dumper really has a pretty awful interface, and that it should be possible to sanitize it and keep it DWIMmish without resorting to filters.

Makeshifts last the longest.

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
