Nested Try Blocks
nWhen an exception occurs and either: (1) no try block statically surrounds the throw point or (2) no catch blocks are found that match the type of exception thrown when a try block is present, then a process called stack unwinding begins.
nIf we are in a function, any automatic variables and formal arguments on the stack are destroyed in the same way as when control returns from a function.
nBut, instead of returning control to the calling function, that function is searched for a dynamically
surrounding try
block.
nIf found, its associated catch block(s) are checked
for a type matching the
exception.
