The order is not specified; f1(), f2(), and f3() may be called in any order. Operator precedence does not control order of evaluation. f1() and f2() must be called before the result of f1() * f2() may be computed, but that doesnt mean that f1() must be called before f2(), nor that both f1() and f2() must be called before f3().
