std.stdio is a module, it looks like a variable. typeof(std) == 
void...
What the? Why does it even have a type?
I can't find a sensible way to distinguish std from any other 
regular
variable.

traits uses something like this (see fullyQualifiedName)

Thanks

import std.stdio;

template isPackage(alias name) {
  static if(name.stringof.length >= 9 && name.stringof[0..8] == 
"package ") {
    enum isPackage = true;
  } else {
    enum isPackage = false;
  }
}

void main() {
  pragma(msg, "Is std a package:", isPackage!std);
  pragma(msg, "Is std.stdio a package:", isPackage!(std.stdio));
}
