Testcase:
```
struct SomeUDA {}

struct S {
    @SomeUDA S opBinary(string op: "-")(S rhs) const pure nothrow @nogc {
        return rhs;
    }
    S opBinary(string op: "*")(S dur) const pure nothrow @nogc {
        return dur;
    }
}

import std.traits;
pragma(msg, getSymbolsByUDA!(S, SomeUDA));
```

This prints "()", i.e. does not return the template function (https://d.godbolt.org/z/Th86qvMGM).

Seems to be fixed by adding `true` on this line https://github.com/dlang/phobos/blob/77adcadf7961dbe1177aa79be381311404a81d46/std/traits.d#L9009 (similar to the `if` condition three lines above it). However, then this slightly modified testcase still fails:

```
struct S {
    S opBinary(string op: "-")(S rhs) const pure nothrow @nogc {
        return rhs;
    }
    @SomeUDA S opBinary(string op: "*")(S dur) const pure nothrow @nogc {
        return dur;
    }
}
```
