This would be a result of Ruby 1.9's new flattening behavior. Quantity is incorrectly assuming here that to_* is a unit conversion attempt and failing; it should probably return NoMethodError instead, which would fix the flattening and probably some other unknown bugs. See

In other news, I don't really work on this anymore, but am happy to give you gem push rights if you're running with it.


I patched it by calling super. I'll change to NoMethodError & submit a pull.

Thanks, I'll take gem push rights. I'm brundage on rubygems. Would you add me as a collaborator on this repo too?
