I have an route endpoint like:
        my $self = shift();

        my $t = {
                id => $self->param('id'),
                attr => $self->param('attr'),
                title => $self->param('title'),
                body => $self->param('body'),
                };


I expect it to end up like
        $t = {
                id => 123,
                attr => undef,
                title => 'Testing 1 2 3',
                body => 'Four score and...'
                };

It actually ends up creating
        $t = {
                id => 123,
                attr => 'title',
                'Testing 1 2 3' => 'body',
                'Four score and...' => undef
                };

        with an "odd number of elements" warning

Do I really have to do
        my $t = {
                id => $self->param('id') || undef,
                attr => $self->param('attr') || undef,
                title => $self->param('title') || undef,
                body => $self->param('body') || undef
                };

        just in case to prevent this behavior? This seems REALLY dangerous in conjunction with DBIx::Class and such.
