Unary plus is not needed here. The expression can be simplified to:


But that draws into question what the program was desgined to do in
the first place, because the result is not used. Also, there is no
semicolon here. Since a CallExpression is not a restricted production,
the program lends itself to the possibility of creating one by
accident, with the addition of any subsequent "grouping operator".
E.g. —


Results in TypeError, as `1` is a number a numbers aren't callable.
