in reply to Shorten one liners with Class::Autouse

Interesting approach. Personally, I shorten one-liners by preloading common modules using a custom ToolSet. 

package XDG;
our $VERSION = "0.02";
use base 'ToolSet';
ToolSet->set_strict(1);
ToolSet->set_warnings(1);
ToolSet->export(
    'Carp' => 'carp croak confess',
    'Data::Dump::Streamer' => undef,
    'File::Spec' => undef,
    'Perl6::Say' => 'say',
    'Scalar::Util' => 'refaddr reftype blessed',
);
1; # true

Used like this:

perl -MXDG -e 'say "Loaded modules:" and Dump \%INC'

-xdg
