A value of type Dynamic is an object encapsulated together with its type. A Dynamic may only represent a monomorphic value; an attempt to create a value of type Dynamic from a polymorphically-typed expression will result in an ambiguity error (see toDyn). Showing a value of type Dynamic returns a pretty-printed representation of the object's type; useful for debugging. |
