Issue summary ------------- #ResourceExistenceAndSize -- Given a `Module` object and a resource name, should there be a way to determine whether that resource exists in that module and, if it does exist, what its size is, without actually opening the resource as a stream? One way to do this would be to introduce a new abstraction to represent resources. [1] Proposal -------- This could be a useful feature, but it is not required for the initial release and could be added in a later revision.
