Recently I've been looking into other languages and talking about them with friends, but we keep coming back to the same realization: for all of its warts, we're always going to always have a soft spot for Perl. Here's just one of the many perlisms I'd miss in another language:
# create a new CGI object with three levels of masking:
# defaults get masked by parameters, and parameters get masked by overrides
my $cgi = new CGI( { %$defaults_ref,
%$parameters_ref,
%$overrides_ref,
} );
