You are asking for elements of the list with <code>()[]</code> construction. Your list generating function may have its own parentheses depending of your preferred coding style: <code>f( list_of_operands )</code> vs. <code>f list_of_operands</code>. Later I call more perlish.<br>
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 <code>'+'</code> symbol before an opening paren which helps parser.<br>
[Discipulus] showed a code written with second style, saving two pairs of parentheses ([id://11140839]).

Also be aware of one more known perl bug: [id://94916]<br>
