Well, just reverse the order of -= in second statement. If you write =-, it will magically work. ;-)
But in the general case, sometimes introducing temporary variables is the simplest solution.
The alternative would be to implement pointwise -= for tuples, which would be extremely confusing since they already implement += with a completely different semantics. |
