in thread Difference in Hash Declaration

Parenthesis () creates LIST:
print 1, 'b', 3, 'd', 5, 'f', "\n";

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

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


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 :)
