in reply to Perl Idioms Explained - my ($foo, $bar) = @{shift(@_)}{qw/ -foo -bar /}

This may be more useful as a parser for simple command line arguments if you call it with {@ARGV}

But there are lots of better ways to do that - this a very lightweight way.

I've recently (last 3-4 months or so) been using named parameter lists for almost all my library code and also using Params::Validate, so my idomatic (OO) code looks like

package Chopper::Reed; use Params::Validate qw/validate_with/; sub psychotic { my $self = shift; my %params = validate_with(params => \@_, spec => { punch => 1, charm => {default => 'JOURNALIS +T', regex = qr/^[CON]/} +, mutilate => 0, }, ); $self->mutilate($params{$mutilate}) if $params{$mutilate}; ... } ... 1;
Note: Chopper Reed is self confessed hitman and was sectioned as a self-mutilator whilst serving time in prison for murder. He has been released, is a successful media personality and author, and recently bought a brewery. He recently left his wife and farm in Tasmania because he "...didn't like the septic loo backing up."
