What I am basically against is the need of removing an easy syntax which can
have problematic side effects if you are not adult enough, in favor of a
complicated library workaround which requires deeper knowledge of Python
(weakrefs, lambdas, early binding of default arguments, just to name three),
and can cause side effects just as bad if you are not adult enough. Where's the
On the other hand, __close__ (out-of-order, recallable __del__) fixes some
issues of __del__, it is easy to teach and understand, it is easy to write.
And, if we could (optionally) raise a RuntimeError as soon an object with
__del__ enters a loop, would your opinion about it be different?
