Re^2: RFC: Creating Dancer2 validation plugin.

sub _register_hooks {
    my $self = shift;
 
    $self->app->add_hook(
        Dancer2::Core::Hook->new(
            name => 'before_template_render',
            code => sub {
                my $tokens = shift;
    ...

I'd have:

sub _register_hooks {
    my ($self, $token) = @_;
 
    ...
[download]

But that's not equivalent! Note the anonymous sub, the second shift happens in a nested subroutine, it uses its arguments, not the _register_hooks' ones.

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

You're right, I completely glossed over that. Thanks for the correction; it's a very important one! I still stand by the assignment rather than shift though.	[reply]
