# A method for forcing list context. If a method uses 'wantarray' then

# calling that method from Template will do strange stuff like chosing

# scalar context. The most obvious offender are RDBO relationships.

# Example of how NOT to test whether or not a customer has contacts:

#   [% IF customer.contacts.size %] ...

# Instead force list context and then test the size:

#   [% IF customer.contacts.as_list.size %] ...
