If you don't want to modify the enum the following code also seems to work. The
main thing is to avoid using __traits(getMember) which could get passed a
non-symbol.
module example;
import std.meta: staticIndexOf;
import std.traits;
struct Attrib {}
@Attrib enum TEST = 123;
void foo() {
foreach(sym; getSymbolsByUDA!(example, Attrib)) {
pragma(msg, sym.stringof); //Prints 123
}
}
The fact that it prints 123 instead of TEST seems to suggest that it is indeed
a problem with the compiler pasting the value where the identifier is used. I'd
recommend taking a look at the implementation of getSymbolsByUDA to see how
it's done there.

This code is *supposed* to be equivalent as far as I know, but it actually
fixes the issue. Change `@Attrib enum TEST = 123` to `@Attrib enum TEST { val =
123; }` and it will compile (you can also make it immutable; basically anything
that introduces an actual symbol).
I think it's because the compiler does not even see the enum; the symbol TEST
is replaced with the actual value at the usage site so it's like you're doing
`pragma(msg, __traits(getAttributes, 123))`, which of course doesn't make any
sense.
