    404 When it happens that the same module is available from more than one
    405 authority, and the desired authority is not specified by the C<use>,
    406 the version lineage that was created first wins, unless overridden by
    407 local policy or by official abandonment by the original authority (as
    408 determined either by the author or by community consensus in case the
    409 author is no longer available or widely regarded as uncooperative).
    410 An officially abandoned lineage will be selected only if it is the
    411 only available lineage of locally installed modules.
    412
    413 Once the authority is selected, then and only then is any version
    414 selection done; the version specification is ignored until the
    415 authority is selected. This implies that all official modules record
    416 permanently when they were first installed in the official library,
    417 and this creation date is considered immutable.

    406 421 use Dog:ver(v1.2.1 | v1.3.4):auth(/:i jrandom/);
