Is there a function like "assign(dest_fusion_seq,src_fusion_seq)" which does
recursive element-wise assignment between any two conformant fusion
sequences(including adapted ones)? I didn't find one but I think there
should be such functionality.
Currently there's 'copy' in fusion/algorithm/auxiliary but it seems not documented yet. e.g. copy(src_fusion_seq, dest_fusion_seq).
I had suggested 'assign' as you expected before, but it's still not there though...
