in reply to Confused by a couple of idioms

PS, I know the backslash is probably a reference, but I've never seen it used before my like this. I just didn't think anything like this was syntactically possible.

$PM = "Perl Monk's";
$MCF = "Most Clueless Friar Abbot Bishop Pontiff Deacon Curate Priest Vicar";
$nysus = $PM . ' ' . $MCF;

    Dont be afraid of that. It's just a precedence issue, precedence of my operator is higher than reference op, no more other mysteries. You are maybe used to open (my $fh,....) it's the same.

      ... And a handy precedence list can be found in perlcheat.

      I have a question about precedence of my. Isn't it a 'named uop', as I thought, or is it absent from precedent list? E.g. 
      perl -wle 'print( my $i ** 2 )'
#Use of uninitialized value $i in exponentiation (**) at -e line 1.
#0

      perl -wle 'print( my ( $i ** 2 ) )'
#Can't declare exponentiation (**) in "my" at -e line 1, near ") )
#"
#Execution of -e aborted due to compilation errors.

      It looks that precedence of 'my' is higher than usual 'named uops'.
