12779	Operations on datasets (join, zip, grid) not available with two user-defined datasets	Moritz Pflanzer <moritz@…>	Raffi Enficiaud	"Operations on datasets (join, zip, grid) are not found by the compiler if both operands are user-defined datasets. The problem is that user-defined datasets are (usually and per the fibonacci example [#l1 '[*]']) not declared in the same namespace as the operator overloads, namely 
{{{
namespace boost { namespace unit_test { namespace data { namespace monomorphic {
}}}

Please find a minimal (not) working example attached.
