Hi Dancers,

I am reading the dancer2 code and can not figure out what the CODE means here.

Could anyone give me some direction? Thanks.

Dancer2/Core/Role/DSL.pm

44 sub export_symbols_to {

 45     my ($self, $caller, $args) = @_;

 46     my $exports = $self->_construct_export_map($args);

 47 

 48     foreach my $export (keys %{$exports}) {

 49         no strict 'refs';

 50         my $existing = *{"${caller}::${export}"}{CODE};

 51 

 52         next if defined $existing;

 53 

 54         *{"${caller}::${export}"} = $exports->{$export};

 55     }

 56 

 57     return keys %{$exports};

 58 }
