Oh, I think it's a good idea to change the source. In terms of backward compatibility you've still got 's' (step into), while the 'n' (next statement) is always a pain when 'n'-ing over sort and map blocks. Of course you can 'c' (continue) to a new location (line), but then you have to stop, break your flow, and work out where you want to go specifically. It's nice to see someone prepared to delve into those murky depths to fix this behaviour to be more intuitive at last.
