One unfortunate sideeffect of allMembers change is that it breaks 
this king of loop:
```
foreach(m; __traits(allMembers, M)) { // M is module
     alias member = __traits(getMember, M, m); // now fails 
because std.stdio is not a member of M
}
```

To fix I needed to rewrite it as:
```
foreach(m; __traits(allMembers, M)) { // M is module
     static if (__traits(compiles, __traits(getMember, M, m)))
         alias member = __traits(getMember, M, m);
}
```
