/// The type parameter `A` allows you to use a different value type; normally you will want it to
-/// be `std::any::Any`, but there are other choices:
+/// be `core::any::Any` (also known as `std::any::Any`), but there are other choices:
///
/// - If you want the entire map to be cloneable, use `CloneAny` instead of `Any`; with that, you
/// can only add types that implement `Clone` to the map.
///
/// Cumulatively, there are thus six forms of map:
///
-/// - <code>[Map]<dyn [std::any::Any]></code>, also spelled [`AnyMap`] for convenience.
-/// - <code>[Map]<dyn [std::any::Any] + Send></code>
-/// - <code>[Map]<dyn [std::any::Any] + Send + Sync></code>
+/// - <code>[Map]<dyn [core::any::Any]></code>, also spelled [`AnyMap`] for convenience.
+/// - <code>[Map]<dyn [core::any::Any] + Send></code>
+/// - <code>[Map]<dyn [core::any::Any] + Send + Sync></code>
/// - <code>[Map]<dyn [CloneAny]></code>
/// - <code>[Map]<dyn [CloneAny] + Send></code>
/// - <code>[Map]<dyn [CloneAny] + Send + Sync></code>
/// ## Example
///
/// (Here using the [`AnyMap`] convenience alias; the first line could use
-/// <code>[anymap::Map][Map]::<[std::any::Any]>::new()</code> instead if desired.)
+/// <code>[anymap::Map][Map]::<[core::any::Any]>::new()</code> instead if desired.)
