Exceptions are a red herring; they are just something you can build if you have dynamic control transfers with unwinding. And if you have macros, or at least some kind of access to the language to bend the syntax. Plus perhaps other goodies like testing whether some object X is of a type which is a subtype of T so you can make exception handling frames decide whether the elevator stops here.
The underlying control mechanism not being there makes the language crippled.
Just give me C. Then I also have forty years of research out the window: but but at least with setjmp and longjmp.
How does Bash recover to the top level prompt when the scriptage fails deeply nested in some function calls? Why, longjmp! I will fake the unwinding if I have to.
