What is the python “with” statement designed for?
...y add it for the sake of completeness: the with statement simplifies exception handling by encapsulating common preparation and cleanup tasks in so-called context managers. More details can be found in PEP 343. For instance, the open statement is a context manager in itself, which lets you open a fi...
lock(new object()) — Cargo cult or some crazy “language special case”?

Has anyone actually implemented a Fibonacci-Heap efficiently?
...
The Boost C++ libraries include an implementation of Fibonacci heaps in boost/pending/fibonacci_heap.hpp. This file has apparently been in pending/ for years and by my projections will never be accepted. Also, there have been bugs in that implementation, which were fix...
