__traits(allMembers, <symbol>) has always been pretty much

a given symbol is public. (i.e. with __traits(getProtection,
Type, member))
Is there a new, approved way of doing this?
I just had to change unit-threaded to get it to compile without
deprecation warnings (and in one case a compiler error). I
don't know of any approved way of doing it, I just did the
first thing that worked, which was to check if something was
private by:
private template isPrivate(alias module_, string moduleMember) {
mixin(`import ` ~ fullyQualifiedName!module_ ~ `: ` ~
moduleMember ~ `;`);
static if(__traits(compiles,
isSomeFunction!(mixin(moduleMember)))) {
enum isPrivate = false;
} else {
enum isPrivate = true;
}
}
Notice the mixed-in import.

i just tried this trick for the first time. it does not seem to
work for me (Windows/DMD32 D Compiler v2.071.1): it alway returns
false, even for private members. is there another way? (i have
the same problem as OP.
