in reply to Difference in Hash Declaration

Parenthesis () creates LIST: 
( 1 => 'j', 2 => 'b' )

[download]
To create a hash, we substitute the LIST for %h: 
my %h = ( 1 => 'j', 2 => 'b' );

Incidentally, LIST is different from ARRAY. To create an array, we substitute LIST for @a: 
my @a = ( 1 => 'j', 2 => 'b' );

    I see a list there but I don't see any parentheses. 

    my @stuff = map $_ + 2, 6, 7, 8, 9, 10;

    Ditto

    Parentheses are used for precedence. 

    my %h = ( 1 => 'j', 2 => 'b' );

    There the assignment operator has higher precedence than the comma operator so the parentheses are required.

      I agree with you. Parentheses don't create LIST, are used for precedence. I'm glad you pointed out my mistake :)
