Not that it helps particularly with this particular expression, but the output from B::Deparse is often enlightening.

I love the fact that perl turns that into a low precedence boolean operator used for flow control and a postfix if. P::C must get righteously apoplectic :)

C:\test>perl -MO=Deparse,p
use 5.010;
 sub apple  { say "apple"  }
 sub banana { say "banana" }
 sub cherry { say "cherry" }

 apple && (banana || cherry)
^Z
sub BEGIN {
    require 5.01;
}
sub apple {
    no feature;
    use feature ':5.10';
    say 'apple';
}
sub banana {
    no feature;
    use feature ':5.10';
    say 'banana';
}
sub cherry {
    no feature;
    use feature ':5.10';
    say 'cherry';
}
no feature;
use feature ':5.10';
banana  or cherry  if apple ;
- syntax OK
