Comment #23 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 don't know what is the problem, I just put a '^self' when encountering problematic case (the empty collection). Like my previous change , I think it does not break anything, but just let RoelTyper less precise for some cases (that are not working)
