[Catalyst] overload/override sub? (Session::PerUser)

[Fernan Aguero]

Hi,

I'd like to overload (or would it be override?) the
merge_session_to_user sub in
Catalyst::Plugin::Session::PerUser to be able to guide the
hash merge (i.e. create new hash value keys for conflicting
keys).

Now, where and how should I do the overriding? Excuse my ignorance
... but I've never done this and searching for 'Perl
overload' always gets me to instructions on how to overload
built-in operators ...

Thanks in advance,

Fernan
