As per title, is it possible to iterate all visible symbols of the current module and of all imported modules and packages? My aim is to find everything in scope that has a specific UDA.

module foo;

import std.stdio, std.array, std.algorithm;

void bar(){}

struct S{}

void main()
{
    // prints ["object", "std", "bar", "S", "main"]
    // how do I discover that "std" is a package?
    writeln([__traits(allMembers, foo)]);

// prints ["object", "core", "std", "KeepTerminator", "GCC_IO", ... ] // strange thing: it looks the same even if I remove all imports other than std.stdio

    writeln([__traits(allMembers, foo.std)]);
}

Thank you in advance.
