There's currently a publicly documented example about using getSymbolsByUDA with private attributes. This only works because the example is in std.traits > dmd -c test.d tuple(a) --- import std.traits; enum Attr; struct A { @Attr int a; @Attr private int c; } pragma(msg, getSymbolsByUDA!(A, Attr).stringof); ---

Could you pinpoint the exact location of the example? I can't find it in std/traits.d

Anyway, this probably is the correct behaviour.

See https://github.com/dlang/phobos/pull/5607

- Started working with https://github.com/dlang/phobos/pull/3827, which allowed getSymbolsByUDA to work on private members - https://github.com/dlang/dmd/pull/5530 caused accessing the field result in a deprecation, but it still worked (and returned both members) - https://github.com/dlang/phobos/pull/5344 has broken this completely. This certainly seems like a regression, but I'm not sure I can put the blame entirely on either of those PRs.

It duplicates the #15335, which - despite the merged PR - still persists or have been revived. *** This issue has been marked as a duplicate of issue 15335 ***
