Redefine is the term in perl-lingua.
In MyApp.pm:
{
no warnings 'redefine';
sub merge_session_to_user {
# your new sub
# ...
# To call the previous implementation if you should want it:
# $self->NEXT::merge_session_to_user(@args);
}
}
The key thing to remember here is that all Cat plugins 'pollute' the $c
namespace, which isa Myapp.
