Comment #5 on issue 586 by cy.delau...@gmail.com: Compute invocation candidates with different strategies seems to be broken http://code.google.com/p/moose-technology/issues/detail?id=586
I gave a solution that make the example working, but I didn't fixed the problem. I flaged the possible bug. Added an example to run (as comment) to highlight the problem. I added a statement for this specific case, where I return self (not able to fix anything).
From moose point of view, it seems to work nicely. I think we just let roelTyper less precise for those specific cases (that means a set of possible types bigger than if the code was running correctly).
