With the -exec flag, B::Concise gives output closer to your example: 
$ perl -MO=Concise,-exec -we'print "Hello, world!\n";'
1  <0> enter
2  <;> nextstate(main 1 -e:1) v
3  <0> pushmark s
4  <$> const[PV "Hello, world!\n"] s
5  <@> print vK
6  <@> leave[1 ref] vKP/REFC
-e syntax OK

by showing execution order rather than the op tree (but no longer shows optimized-away ops and can make branching ops less clear).
