What is the global interpreter lock (GIL) in CPython?
...
Python's GIL is intended to serialize access to interpreter internals from different threads. On multi-core systems, it means that multiple threads can't effectively make use of multiple cores. (If the GIL didn't lead to this problem, most people wouldn't care about the GIL - it's only being ra...

Why does the Scala compiler disallow overloaded methods with default arguments?
...
I'd like to cite Lukas Rytz (from here):
The reason is that we wanted a deterministic naming-scheme for the
