(I have tried with allMembers too.)
It's like it won't pick up the member that is added using a
mixin at line 22.
```
mixin("ubyte[" ~ to!string(__PADDING_SIZE__) ~ "] __PADDING__"
~ member ~ ";");
```
It's because the identifier starts with two underscores. Such
identifiers are reserved for internal use, and apparently
they're ignored by some (all?) __traits.
I'm not sure if this can count as a bug, but it doesn't look
just fine either.
Smaller test case:
----
struct S
{
int foo, __bar, baz;
}
pragma(msg, __traits(allMembers, S)); /* tuple("foo", "baz") */

Thank you. I was not aware of such a gotcha.
Should definitely be documented or yield an error/warning if
attempted in user code else you end up with hidden "bugs" like
this
