ref lost to opDispatch

What exactly is the effect of this? Does it make all of args ref 
parameters when instantiated?

In which case it doesn't solve my real problem where I have more 
that 100 functions with all sorts of parameter lists being 
dispatched and I only want ref where it's prescribed.

Is the behavior of the code I wrote a design feature or a bug?
