Not exactly. If you set up a try-catch, an exception handling frame is
set up. An exception handling frame is not necessary in order to throw
an exception, it is only necessary to:
1. catch exceptions
2. unwind exceptions (run destructors)
What happens if a nothrow function does throw is that your destructors
and finally clauses may not get run in between the throw and the catch.
nothrow void foo();
will_never_execute(); // even if foo() throws
because the compiler will optimize away the finally clause.
