Why doesn't c++ have &&= or ||= for booleans?
...

int i = 2;
bool b = *reinterpret_cast<bool*>(&i);

How do arrays in C# partially implement IList?
...() call fails for a concrete array type with "Interface not found". Yet a cast to IEnumerable<> works without a problem.
This is quacks-like-a-duck typing. It is the same kind of typing that creates the illusion that every value type derives from ValueType which derives from Object. Both t...
