Your answer mentions exactly what I'm trying to avoid - that the user of User knows about User's implementation: 
#  izut said
use Lookup::Remote;
my $lookup = Lookup->new({ remote_uri => $uri, });

This to me looks like User's use of Lookup::Remote is not hidden, and thus breaks the interface between User and code using it. In other words, any code instantiating a User does not and should not need to know that there could be a vast amount of code tucked away providing the user information (or the ultimate source of that information); merely that when $user->info() is requested, it is available.
