Nice change!
This is also a step towards scopedgraphs, which will probably
be yet another entry in backendoptimization.py
The main difference would be to identify subgraphs with
a single entry and exit point. These can then be rendered
by nesting them into a block and avoiding to transfer the
implied variables over the entry link at all.
