borrowed pointers vs ref

[w0rp via Digitalmars-d]

The first thing that comes to my mind is applying this somehow to 
the (T) vs (ref T) function problem. (const ref, scope ref, 
references to r-values, you know the problem.) At the moment I 
just follow this pattern.

void foo(ref const T bar) {
     /* ... */
}

// Second overload to make r-values just work.
void foo(const T bar) {
     foo(bar);
}

auto ref sometimes works, sometimes it's more trouble than its 
worth.
