Plus() currently doesn't support that, which limits its use for certain scenarios.

We are well aware of this issue, and it's not just plus, but all binary element-wise operators. It will finally be resolved when we get a chance to work on cleaning up the backend, which, apart from expressibility issues also has perf issues, especially with the VS 2015 compiler.
