Yup, every one of those is very familiar. I go through periods where I screw up one of them constantly, then I get better and start screwing up another one.

The one missing one from that list that I have recently picked up is

  my %h = ( name = 'Bob',
            age = 37,
           .
           .
           .
          );

Never used to do that, but recently I've done it half a dozen times.
