IDL43 — Importing a name scope recursively imports all name scopes nested within it

The section Imports contains

The effects of an import statement are as follows:

• [...]
• Importing a name scope recursively imports all name scopes nested within it.

This looks counter intuitive to me.

Example:

module commontypes {
   module nested1 {
      enum RGBColor { RED, GREEN, BLUE };
   }
   module nested2 {
      enum TrafficLight { READ, YELLOW, GREEN };
   }
};

What happens if another module does "import commontypes"?

If, as the standard says, all name scopes nested within "commontypes" are recursively imported then this would lead to errors:
The enum values RED and GREEN would be directly visible and would be in conflict with each other.
