…he main module being scanned For example, when scanning a source module `Foo`, which, when depending on module `Bar` causes a cross-import overlay `_Foo_Bar` to be added, do not add this cross-import overlay when scanning `Foo` itself. For example, if `Foo` adds a dependency on `Bar` itself in its own dependency graph.

For example, when scanning a source module
Foo, which, when depending on moduleBarcauses a cross-import overlay_Foo_Barto be added, do not add this cross-import overlay when scanningFooitself. For example, ifFooadds a dependency onBaritself in its own dependency graph.These scenarios otherwise can typically result in a dependency cycle, since modules participating in adding a cross-import overlay are, themselves, depended upon by the cross-import overlay module.
