You are asking for elements of the list with ()[] construction. Your list generating function may have its own parentheses depending of your preferred coding style: f( list_of_operands ) vs. f list_of_operands. Later I call more perlish.
In both cases if you need to apply one more function, you need either one more pair of parentheses (using former function writing style), either no-op '+' symbol before an opening paren which helps parser. Discipulus showed a code written with second style, saving two pairs of parentheses (Re: set context for method's return values). Also be aware of one more known perl bug: why does 'print ("hey)")' give a warning? In reply to Re: set context for method's return values
