Re^2: Confused by a couple of idioms

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` [download] `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.` [download] It looks that precedence of 'my' is higher than usual 'named uops'.
