I did this. It's super ugly and even has `__traits(compiles)` in 
there, but as a quick and dirty solution it served well enough.

```d
void printPublicMembersOfModule(string module_)()
{
     mixin("import thisModule = " ~ module_ ~ ";");

     foreach (symstring; __traits(allMembers, thisModule))
     {
         alias symbol = __traits(getMember, thisModule, symstring);
         static if (
             __traits(compiles, __traits(getVisibility, symbol)) &&
             __traits(getVisibility, symbol) == "public")
         {
             pragma(msg, symstring);
         }
     }
}

void main()
{
     printPublicMembersOfModule!"std.stdio"();
}
```
