15.2 Constructors and destructors
1. As control passes from a throw-expression to a handler, destructors are invoked for all automatic objects
constructed since the try block was entered. The automatic objects are destroyed in the reverse order of the
completion of their construction.
3. The process of calling destructors for automatic objects constructed on the path from a try block to a
throw-expression is called “stack unwinding.” If a destructor called during stack unwinding exits with an
exception, std::terminate is called (15.5.1).
15.3 Handling an exception
9 If no matching handler is found, the function std::terminate() is called; whether or not the stack is
unwound before this call to std::terminate() is implementation-defined (15.5.1).

Still, the batting template looks locked in:
• Attack early, even after early wickets.
• Keep left-right options when possible.
• Let Surya play as the tempo-setter, not the fixer.
That’s a modern T20 identity, and it’s getting results.
