    It does. Try with print instead of return to see.
      Do you mean the priority of and is even lower than return???
        Indeed it is, if you want something evaluated put it in parenthesis to be sure
        return (1 and 0);
        returns 0 as you would expect.

        print "Good ",qw(night morning afternoon evening)[(localtime)[2]/6]," fellow monks."

        See perlop for the precedence table. not, and, or, and xor are all at the bottom of the table.

        Indeed. and 'n or are good for control flow such as replacing simple error-handling ifs, while && 'n || are your standard Boolean logic operators.
