    BEST PRACTICE: Group file contents around needed data

/**
    In summary:
    Im simple (augmentation), the (module) file and the augmentation file (do not) share their (private state).
    Augmented module (properties) may only (access) the (private) data from their file's (closure).
    (Private) data from the (original) closure (will not) be lost, and (will) be accessible to all original (properties) that referenced it.
