Hello,

The code below:

================
import std.traits;

enum Attr;

class MyClass
{
    private @Attr int a;
    static assert(getSymbolsByUDA!(typeof(this), MyClass).length == 1);
}
================

does not compile as static assertion fails. Making the filed a public makes it compile properly. Should I file a bug or is by design?

getSymbolsByUDA seems to have some visibility thing going on. Related to https://issues.dlang.org/show_bug.cgi?id=17973 perhaps? Though that only gives deprecation warnings, not errors.

It's definitely a bug!
