C++ language pickiness

[Ross Younger]

Destructors should never throw.
The jury is out on whether declaring exception specifiers in general is worthwhile.
Should destructors should be nothrow? i.e.
virtual ~SomeClass() throw() { ... }

throw() is deprecated in c++11.
Since c++11: void f() noexcept;
If an exception propagates from a noexcept function, that's an insta-termination offence.

Consider using nullptr instead of NULL or 0 constant.
