Imagine you wrote a function

Syntax wise we could force you to say foo(&something).
Which fits perfectly in the existing pointer syntax.
No it does not, because then this becomes ambiguous:
foo(ref int a);
foo(int* b);
...and furthermore, what would we do with this:
void foo1(T)(auto ref T a) { foo2(a); }
void foo2(T)(auto ref T a) { /*...*/ }
?
Personally I stay away from ref precisely because of it's silent
caller syntax.
