Remote pointer
RemoteRef: reference to some heap object (potentially remote)
A reference to a heap object. Potentially in a remote heap! These are allocated and freed explicitly.
Make a reference to a local value that we can send remotely. This reference will keep the value that it refers to alive until freeRemoteRef is called.
Convert a RemoteRef to its carried type. Should only be used if the RemoteRef originated in this process.
Release a RemoteRef that originated in this process
ForeignRef: RemoteRef with a finalizer
An RemoteRef with a finalizer

NFData (ForeignRef a)Defined in ghci-9.14.1 · GHCi.RemoteTypes
Create a ForeignRef from a RemoteRef. The finalizer should arrange to call freeRemoteRef on the RemoteRef. (since this function needs to be called in the process that created the RemoteRef, it cannot be called directly from the finalizer).
