I typically see classes with delegated methods use a
default => sub { {} },
or
default => sub { [] },
stanza in the definition(s) depending on whether they're Hash or Array traits.
I agree this should be better documented though

Here's a sample of the code in question (assume the appropriate pragmas for
type constraints):

Side note, I'm using namespace::sweep if that makes a difference.
