ehm, there's a typo ...

...if you want to activate extra options like parens to emphasize the precedence you need to prepend a minus, i.e. -p

$ perl -MO=Deparse,-p
 use 5.010;
  sub apple  { say "apple"  }
  sub banana { say "banana" }
  sub cherry { say "cherry" }
 
  apple && (banana || cherry)
__END__

... yadda ...yadda ...

(apple() and (banana() || cherry()));

UPDATE

well it's still not too clear about left-to-right.

I know there is somewhere an option to combine the optree with readable code, not sure if in B::Deparse or B::Concise or B::Terse

UPDATE Terse and Concise have the option -src but it doesn't help that much, cause it's line based.

Cheers Rolf
