current "ref" args state.

[w0rp via Digitalmars-d]

Explicit or implicit pass by reference at the call site is a 
political argument and it is highly subjective. I'm used to the 
current state of affairs (due to coming from C++) and I don't see 
anything wrong with it. If you can't tell from a function's name 
what its going to do with its arguments, something is probably 
wrong. If you aren't using const or immutable until it hurts, 
something is probably wrong.
