          Issue ID: 18314
           Summary: std.traits.getSymbolsByUDA only considers the first
                    symbol of an overload set
           Product: D
           Version: D2
          Hardware: x86_64
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: phobos
          Assignee: nobody at puremagic.com
          Reporter: dechcaudron+dlang.issue.tracking at protonmail.com

Consider the following code:

```
enum lol;
enum lal;

struct A
{
        @lal
        void foo();
        @lol
        void foo(int a);
}

void main()
{
        pragma(msg, "Tagged with @lal:");
        static foreach(alias member; getSymbolsByUDA!(A, lal))
        {
                pragma(msg, __traits(identifier, member));
        }

        pragma(msg, "Tagged with @lol:");
        static foreach(alias member; getSymbolsByUDA!(A, lol))
        {
                pragma(msg, __traits(identifier, member));
        }
}
```

When building, `foo` only shows up in the first foreach, not in the second one.
