just a nitpick: it doesn't mention setjmp/longjmp in C - that is even less restricted and allows you to jump between functions. Well it is used to do something

just a nitpick: it doesn't mention setjmp/longjmp in C - that is even less restricted and allows you to jump between functions. Well it is used to do something like exception handling in C; but don't do that if C and C++ got mixed as your automatic objects in C++ will not get destructed.
