Please try changing this line to: return $self->includes($remote) & ($remote->{id} == $item_id); I think it's probably a harmless warning. Please respond to this message letting me know how you get on!

I sure hope `make test' didn't pass with the code as above, that would be a bug in itself :-) It may be syntactically correct, but that function isn't returning logical truth. It's returning a Tangram::Expr object. It's using the bitwise "&" because the logical "&&" is seen by Perl as a language construct, not an operator, and hence not possible to be overloaded via "use overload". Perhaps Perl 5.8 wants the precedence *really* explicitly labelled: return($self->includes($remote) & ($remote->{id} == $item_id));

This should be fixed in Tangram 2.06 with Perl 5.8.1-RC2+
