You're mixing up order of evaluation with operator associativity. The **
operator is right-to-left associative, this means x ** y ** z == x ** (y
** z). Evaluation is left to right, where it matters [i.e. if one or
more of the elements here were an expression with side effects]: first x
is evaluated, then tmp=y**z, then x**tmp. These are two entirely
different concepts.
