Another option: use -vcg-ast, and have the compiler tell you

The output's not that useful...
```d
import object;
struct S
{
int n;
void opOpAssign(string op)(S rhs) if (op == "/=")
{
n++;
}
void opOpAssign(string op)(S rhs) if (op == "/")
{
}
}
unittest
{
S a = S(1);
S b = S(2);
a.opOpAssign(b);
b.opOpAssign(a);
assert(a.n == 2);
assert(b.n == 3);
}
...
```
With this tiny example code it's clear by the end when there's
only this one template instantiation:
```d
opOpAssign!"/"
{
pure nothrow @nogc @safe void opOpAssign(S rhs)
{
}
}
```
