The spec says:
"
The only place a refcounted Throwable is ever created is when the
following statement is in the user code:
throw new E(string);
"
What other typical throw cases will _not_ be allocated on the GC?
My understanding is none.
So for example:
auto ex = new Exception(string); // heap allocated
throw ex;
It entirely depends on you immediately throwing the exception because
otherwise, you may have stored a pointer elsewhere. Because classes
(exceptions) cannot be truly refcounted on copy, you need a very
controlled environment to ensure the ref-counting works.
