          Issue ID: 23966
           Summary: [REG2.102] Cannot use traits(getAttributes) with
                    overloaded template
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: regression
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: johanengelen at weka.io

Testcase:
```
module test;

@("gigi")
void fun() {}
@("mimi")
void fun(int) {}
void fun()(int, ulong) {}

void main()
{
    static foreach (t; __traits(getOverloads, test, "fun"))
        static foreach(attr; __traits(getAttributes, t))
            pragma(msg, attr);

}
```

This no longer works with dlang 2.102, even though the release notes say that
this is correct code.
https://dlang.org/changelog/2.102.0.html#dmd.deprecate-getAttributes-overloadSet
It errors on the fun()(...) template.
