--- Comment #1 from Claude <claud...@live.fr> ---
Actually it is not certain that is a Phobos problem, as replacing the
moduleName template within std.traits by that reduced code:
template moduleName(alias A)
// __traits(parent) returns "module modName"
// so we just retreive "modName"
enum moduleName = (__traits(parent, A).stringof)[7 .. $];
... leads to a wrong result (ignoring the fact package names are not prepended
to the module name in that code of course, which is not the issue here anyway).
