This sounds so great! Thank you for improving `in`!

I've literally yesterday written some new code with `const scope
ref` in almost every function to pass large, complex structs.
Occasionally, I had to store rvalues temporarily to pass as
lvalues (non-templated code). I would rather simply put `in` on
those parameters :-) It's a lot easier to grasp function
signatures only using `in` and `out` on parameters (and their
effect/purpose being immediately obvious to new D programmers!)
