If a parameter is marked as ref then you have to assume it will be

now imagine that you're reading some code:
foo(a);
vs:
foo(ref a);
which code style is easier to read without constant jumping into
documentation?
Is this ever actually a problem in practice?
yes. aliced has this syntax for a long time. for a reason. and i must say
that i'm adding alot of random features to aliced, but very little of 'em
survives.
Anyway, having to add ref or out at the call site will greatly hamper
metaprogramming.
not more then "&" does. except with `auto ref` -- which is misdesigned
feature anyway (forcing programmer to do the work compiler can do without
any external help is not a good design; besides, compiler can do that work *better*).
