Source[det]portray_blob(+Blob, +Options)
Portray non-text blobs that may appear in output terms. Not really sure about that. Basically such terms need to be avoided as they are meaningless outside the process. The generated error is hard to debug though, so now we send them as '$BLOB'(Type). Future versions may include more info, depending on Type.
